5 of 5 Fantastic Cell!! January 28, 2019
Reviewer: Daniel C. from Knoxville, TN United States  
This cell is absolutely fantastic.  Same exact high quality brand of Sony before the buyout from MuRata.  So that hasn't changed at all.  This cell is near exactly identical to the Samsung 40T and performs near exactly the same in test except it actually runs a few degrees cooler @ 30A CDR.  I highly recommend this cell to all who have very high expectations and desires from their device(s).  These are 100% Legitimate and Genuine cells.

5 of 5 Great Battery! January 24, 2019
Reviewer: dj alcazar from murrieta, CA United States  
I’ve been using the samsung 30T 21700’s before I tried these. It’s a great battery and it lasts a good amount of time depending on what resistance you’re at. the shipping was super quick, I ordered monday night and got them by wednesday afternoon.  I highly recommend this battery and this website.
