## Customer Reviews

### ⭐⭐⭐⭐⭐ Good
*by W***G on 6 November 2018*

Have used 3 of them so far & they all work perfectly on our Paxton Net2 access system.The only problem some people may have is that the wristband is a bit on the small side ( my wrist is about 20cm/8" in circumference and it's a tight fit )

### ⭐⭐⭐⭐⭐ Worked really well
*by D***D on 5 October 2019*

These have worked without any problem. Comfortable to wear. Worked after swimming in the sea. Would be nice to get them in a smaller size too as they might be a bit big on a female wrist.

### ⭐⭐⭐⭐ JUNE 2021
*by E***. on 26 June 2021*

Mine worked a treat.. re-coded straight off the bat and are lovely to both look at and touch... used mine in my home built car alarm and they are 100%.
