Excellent product

I have a number of chargers, including Nitecore, Opus and Miboxer. After my one Opus C100 packed up, I was looking for another single bay charger specifically.
Did a bit of research on replacing the Opus but landed pricing was a bit steep. I happened upon the UM2 charger which, although a double bay, met all my requirements (Except not being capable of a 2amp charge).
Pricing on the UM2 (From Downtown Vapoury) is unbeatable and the charger performs exceptionally well for a wide variety of cells. Really impressed with this.
Shipping was very fast and easy.

My previous charger was the new i2, after exactly 1 year, it stopped charging, although all lights were on, all it did was a low humm.. I bought this UM2 & simply wow. It looks & feels sturdier, with tons of info on screen, seems to charge better & even revive dead batteries.. Lastly, thanks to a great team at Downtown, it arrived in record breaking time to save my life.. AAA+++
