"Not worth it!" Edit - excellent customer service and product!
Does not charging or hold charge at all. Bought it to replace the battery for Anki Cosmo. Does not works at all. ... Old review.New review - Edit: Seller resolved the problem by sent me replacement battery and it works perfect. Doble capacity of new battery mean much more time fun with the robot. Little extra time to disassemble and put together robot twice, but now I am kind of "expert" doing it.

They work
Used two of these batteries in series to repair the wifey’s facial gizmo. Worked like a charm. The kit is supplied with several connectors. Cost was $20 or so for the repair. Saved hundreds of dollars.

Smaller sizes do not meet the specs
I bought multiple sizes of these, and while the bigger sized met the specs as far as I can tell, the smaller ones do not. I was buying these because of the 3C discharge rate, however the 602035PL 380mAh battery maxed around 1.5C (585mA) instead. The big 5050 size over delivered a bit, and the 952259PL 1400mAh delivered right at 3C (4200mAh). Since my project requires a discharge of at least 1.8C (700mAh) the smaller batteries I really wanted to be able to use will not work (I need load not duration).

Great value and easy to install
Too early to rate on battery life and longevity. But, delivery and price were excellent!

Capacity is 12% short of rated.
Sold as 9500 mAh - Measured at 8370 mAh capacity (at 70 Farenheit into 4 Ohms). The built-in protection circuit cuts out at 3.25V. Charging starts out less than 2A and drops rapidly below 1.5A. This seems very slow. Weighs 170g.

Beware if you're buying this to fix a ES100
My Radsone ES100 needed a new battery, but the original was discontinued. An iFixit guide took me to this as a viable replacement. It will not fit, please exercise caution if you're buying it for this purpose, but I did sort of anticipate that. I'll probably make myself a custom little case or modify the old one.I did feel a need to dock 1 star as the wires included seem like absolute overkill for a pouch cell of this size and it made them extremely difficult to work with. Seriously, feels like 20 gauge...

Replaced battery in FLIR camera and it's like new.
Had to solder the wires into the device because I couldn't find a battery with the right connector but after doing it, it works great and lasts forever because it is a higher capacity battery. (Didn't quite fit back together because this battery is a little thicker than the old one but a little duct tape and I was good to go.)
