The cells look decent. Not sure if they are any good or not since I have never used them. Speedtech RC sells packs (by more well know matchers) with similar numbers for about the same price.
The only real reason that I am commenting on these cells is because I hate when matchers sell packs as this one does. Click on the link above and look at his "6 PRO V Cells." Look at the numbers on this pack. He matches them using run time only and not necessarly by voltage (assuming this image is representative of the packs he cells). He has cells in the same pack that run from 1.170 - 1.177. Drives me nuts!
Matchers that do this are probably small matchers and they don't go through as many cells as some of the larger matchers do. Therefore they might not have a choice and have to match using run time as the main consideration.
I am not saying this is bad...I just hate buying a pack and seeing the staggered numbers like this!
