I have 16 and I've had them and used them regularly for 3 years and counting. I bought their charger too at the same time rather than some generic one - whether or not that makes a difference. I'd been looking for something decent for a while and a sound recordist I work with recommended them - he uses them for all his kit and it's never failed him. Def the 'pro' version though rather than the standard eneloop ones. I reckon I've charged them 100+ times. They say the pro can be charged 500 times, the standard set can apparently be charged more times (2000+) but lower capacity and lower current.

I used to use those Calumet ones for flash too and they were shit. Had to take dozens with me at a time. These are great and hold their charge for yonks.
