Works great. I think I'd like it if there was an option where there was a hole at each end. Also an option where there is no holes for the pin and LED. I don't need those holes, I already paired it before I inserted it in the case.
One side of the smaller half split for me a little bit so I just added some glue over the top. I wish the thickness was a little higher on that side.
The sensors fit very well with their sticky still on, and are in no danger of falling out.
So, even with those comments, I still recommend these.
