We also used these in our church's wireless wearable mic packs after having a poor experience with Enloops. The Enloops couldn't get through our three morning services. Based on my history with Powerex, I bought more of these and the problem was solved.
If you are looking for a solid rechargeable battery at a good price, you've found it with these Powerex.
I think I've gotten to, about, the 100 or so charge mark on all of them. When I charge them up to full (using my ThruNight MCC-4 charger) it takes a couple weeks and they are down to 50% or so ... and that's just sitting in the PowerPax cases I keep them in. I've conditioned them by draining and charging slowly (La Crosse Technology BC1000 charger) and nothing seems to bring them back.
I'm not happy with them at all. They get 3 stars because they worked for the better part of 2 years without issues ... but, since they are marketed to be long lasting and all that stuff, it's disappointing. However, if they are being used they last about 66% as long as I would expect.
Out of the batch of 16 I bought 1 one bad in the first year and one more went bad the second year.
