  1. Dawn Middleton

    Exactly as stated. Hopefully protects the car from would-be thieves!

  2. AlanB

    Just the job!

  3. Tim Butler

    Excellent product and speedy delivery

  4. Rachel

    After being the victim of a cyber attack, I needed something that would block signals from my hacked phone until I could get it professionally wiped, and to protect my new phone – these pouches are awesome as they stop everything, not just Bluetooth and NFC. I have bought several; my only slight gripe is that my S21 Plus with a protective case only just fits inside and it’s a bit of a squeeze, so they could be very slightly larger. Otherwise, top marks!

  5. Paul Gillespie

    Brilliant value and it works,gave to family as a gift

  6. Michael stewart

    I have purchased the defender signal blocker and also the defender “mini” signal blocker. These are the only pouches I’ve found that actually work and block signals. The mini pouch, perfect for just your key fob, with a key ring on the back for for the rest of your keys.

  7. Terry Cotterill

    Excellent product, excellent service. Order quickly delivered.

  8. Elaine Brear

    Good quality strong fabric easily fits key fob /phone inside. Would recommend.

  9. Andrew Hilton

    I ordered 2 of these Defender minis as I am having trouble with the back doors on my Mini Clubman they keep opening & it is very annoying, so I did a bit of research & found these Defender minis. They arrived very quickly & looked great & well made, I put my keys on the Defender & went to my car & when the key was in the pouch the doors would not open as soon as I took them out normal service was resumed. I would recommend these to anyone if car key security is an issue for you especially with keyless start cars as mine is as they are an effective piece of kit, easy on the pocket & easy on the wallet & give me good piece of mind that my doors will not open on my car without my knowledge & also your keys when in the Defender can not be scanned by thieves.

  10. Loraine

    Brilliant as stated on the website- adds to a feeling of security in theses uncertain times

  11. Stuart Cowland

    Just ideal for pocket and also indoors

  12. Roger Brown

    The wonderfully inefficient Royal mail managed to lose the order but when I queried the delay two more pouches were sent out straight away. No hassle and brilliant service. AND the pouches work superbly. Place your keys on the bonnet in the pouch and the car is secure. Excellent!

  13. Adam Brodie

    No need to have sleepless nights worrying if your car will be their when you get up in the morning.

  14. stephen

    It works

  15. Howard Vollans

  18. Philip Baker

    Very quick delivery and the product does exactly what it’s supposed to do. It’s very efficent even up to the car there’s no signal. Highly recommended

  19. CollectPlus Customer

    Does what it says on the tin. Good price

  20. John Bloor

    Received, a couple of days after an email saying order completed. I’ve previously bought several of these pouches from the well known auction site. ALL worked well on receipt and yet when I checked the signal blockers capability around six or seven weeks later, non of the pouches work. I have purchased cheap and expensive pouches and found non block any singles after 6 or 7 weeks. I wait to see if this pouch is any different. It looks nice and it works well on day one. I live in hope………..?

  41. Michael Gill

    Looks well made and hopefully will provide the degree of protection required (still to be tested)

  42. customer

    These are the second set of pouches we have bought. The first set lasted approximately 5 years but eventually the velcro gives up allowing for signals to penetrate them. I am very pleased with them as they do work and some of my family have also bought them on my recommendation.

  43. Mike Hallard

    Excellent product – lives up to it’s reviews and very good price.

  44. Sue

    works well

  45. Andy F

    Can’t fault the product, has a high quality look and feel.

  46. Eddy Denim

    Great product to protect your car from thieves who use scanners to pick up signals from your keyless car fob. Also blocks mobile phone signal when your phone is placed inside.

  47. John Roberts

    It works but it is a bit big just for keys

  48. Linda Batting

    Was delivered very quickly. Good size for me to find in my handbag. Thankyou

  49. Sid

    Does exactly what it says on the webb site nice and neat would recommend this poch

  50. Mrs Paula Houghton

    These are really good and they work. They were recommended by the Police in our area as there had been a lot of car thefts recently. I keep one in my hand bag for when I’m out and about and one indoors so my car key signal cannot be picked up by anyone outside my house. You really do have to take it out of the pouch for the car key to open the car door even if holding pouch in your hand. I thoroughly recommend these Faraday Pouches.

  51. Errol

    It actually does what it says on the tin. Seems to completely block the signal like it says it does. Tried it with two phones linked via mobile hotspot, even sitting on top of the pouch the signal had stopped transmitting from inside. Worth every penny.

  52. Andy Waine

    Great product provides some assurance against car and phone hackers. Good price too. Win win all round.

  53. Jane Wandsworth

    Products look well made. Size good; would fit most car keys or phones without being excessive. Bought as a present so cannot comment on how effective they are ( hence reason for only 4 stars) but research before buying showed them to be better than most.

  54. KeithJ

    Two pouches in the bag great value and they work very well

  55. Ann Docherty

    Everything I needed at a very good price

  56. Kim Mason

    These bags really work, well made and a great price.

  57. Nigel Jones

    Does exactly as described.

  58. Maggie

    Great product !

  59. Magic

    Absolutely brilliant, well made and super effective. My phone goes out of service as soon as it’s inside the case. Service returns about 5 seconds after taking it out again. It’s great for when I want my phone on, but don’t want to be contacted. The bonus of the case is that it also protects against any harmful EMF radiation coming from your phone, especially if you sleep with it anywhere near you at night time. 5 stars! ⭐️⭐️⭐️⭐️⭐️

  60. Emma

    Product came very quickly, well packaged. Wallet for keys is very well made

  61. AB

    Excellent, highly recommend. Works great.

  75. Roy Wiggins

    These work perfectly and are simply awesome vslue. Highly recommended.

  76. Just Another Joe

    Product made from good material that should last a long time. Went for the medium size so could get not only car key but other keys and key fob in too.

  77. Gwyn Thomas

    Effective pouch protecting the car keys unlike previous ones I have tried

  78. Stephen Woolston

    Fit keys and phone in if needed, however if you phone is too big you might struggle.

  79. davidfletcher

    good product

  80. Emeka Ezekude

    The name says it all. Defender Signal Blocker. Indeed it really defends and blocks. What more do you want. 100% genuine product. It does what it says and it is more than value for money.

  81. Richie

    Product is very good quality at a competitive price

  82. Dave Lawton

    Absolutely fantastic product & great price would recommend to anyone keep up the good work.

  83. Rosie

    Excellent value for money as you get 2 pouches. They hold car keys and also a phone which is an added bonus. We were advised to buy these by a friend mainly to protect against car theft but it’s great to have the option of using it for phones as well.
    The pouches are well-made from strong material and not too bulky. Would recommend.

  84. Stuart

    I bought the Defender key protector and it did work well for about a month. However, last night discovered I can know open and close my car and even start it while it is in the pouch. So in other words its now pointless. I appreciate things get worn, but a month is not really acceptable. Advise look at alternatives.

  85. Marion Saunders

    Good service, fast delivery. Very happy with product.

  86. Mike

    Great product at a good price

  87. Daniel

    A faraday pouch that really works.

  88. Jonathan

    Appears to be larger than the previous version but still works great!

  89. Jeremy Marshall Roberts

    Very effective. If car keys in the bag, car will not start even though it is in the central open pocket

  90. Mike

    I bought the Defender Blocker Mini via Amazon in December for a planned new car. It may have worked OK previously but today I discovered I can open the car without removing the key from the pouch and even drive my car like this. I only had to take it out of the pouch to lock the car. Fortunately I belt and braces at home and keep the key in the pouch in a tin as well.

  91. S Butler

    I bought the Defender blocker key pouches via Amazon and it worked for about 4 months, but suddenly the car was opening as I approached it even though the key was securely in the pouch. As it was a twin pack, I moved the key to the unused pouch and it successfully blocked the signal again. However, this didn’t last long and only 6wks later the car is opening again with the key inside the pouch!! Disappointed and will be contacting Amazon

  92. Richard Portsmouth

    The Faraday pouches block the fob signal really well.

  93. M Symes

    Good quality product which arrived promptly.

  94. David

    They work!

  95. Mr Gwyn Owen

    Bought a car key pouch from Defender Security Products. Reviews say it’s the best on the market and I have proved this. Took the key right up to the car inside the pouch and it did not open the car

  96. Caroline Tisdale

    Quick delivery just way too big for my key card,wish I knew it was so big !! But it works and my phone fits in it snuggly ,just wish size was better for card key apart from that excellent

  97. Grandad Bristol 1958

    Value that works.

  98. Mr ROBBINS

    Works perfectly and arrived in good time, good quality product

  99. Paul overfield

    I have just purchased a faraday car key pouch .it works perfectly. I must say I have bought several from other companies and this is the only one to work fully .I would highly recommend this company 10/10

  100. Les Brothers

    Purchased a couple of Defender Signal blocker pouches tested them by putting the keys in them and they worked could not open the car door/boot. Also purchased the larger version for the spare keys all very well made.
