Bests & Worsts Reviews from Amazon

Not a review I wanted to write but I've received about 4 or 5 packages of bad batteries in a row. This brand used to be my go to. I am a photographer that uses a speedlight constantly and I would take several hundred photos per day with the flash and these batteries USED to do the job, and then seem to take about a MILLION recharges and perform flawlessly before I finally had to replace them. Now? I can't power my computer's MOUSE on a fully charged battery that I used for less than a month. They are absolutely worthless to me. One bad package? I can take it. It's been several in a row now, and I'm now going to change brands. It's not the charger, I've charged them in several different chargers I have and none of them perform like they used to, and lose their charge almost immediately even when not used. Super disappointed. And it's probably just bad luck and other people are getting batteries like I used to get but I just can't deal with 4 or 5 bad packs in a row now, I rely on these things for a job and I can't trust them anymore.
