Excellent price & delivery, just the job.
Small compact, does what it says,great buy.
I ordered these online and within an hour I received an email to say that they have been despatched, I received them the next day. Wonderful service!! Of course you have to check that they work and they certainly do, they are just big enough for my Volvo keyless remote and I like the attachment rings both inside and outside the case. Well done!
Fantastic 5 stars Bought 2. Most of our neighbours now have then after we had our cars stolen.
Good quality. Keys fit perfectly, Fast delivery. Would recommend
Really pleased with my order…… early Christmas present for hubby’s new car. Feels much safer using the signal blocker!
Have a keyless car card. Went to car with key in pouch. Car inactive. Product works fine.. Bought 2.
Amazing product. Just the right size for car key. Does what it says & received it within 2 days of ordering.
Really excellent. Very effective at blocking signal.
Have tried this out and it blocks the fob’s signal fine. I’ve also found that it’s better to remove any existing key ring/tag and use the supplied ring in the pouch.
