Superior Customer Service December 3, 2018
Reviewer: Kkenneth Bruno from BrBighton, MA United States  
First and foremost I would like to thank the Nitecore store for their incredible customer service.  I received a charger that was not functioning properly and I immediately contacted them about an exchange.  In less than an hour I received a message with an apology and a promise that they would personally inspect the replacement before sending it out.  There was also a tracking number for the replacement.....no hassles about returning the defective charger, no repackaging and paying for return shipping....nothing of the sort.  They just sent a replacement without hassle or delay.  Finally, a company that gives a damn about the customer and their reputation.
The charger is great...charges up my 21700 batteries efficiently.  The 21700's fit really well and are easy to get in and out of the slots.  If you have batteries longer than 72mm they will easily fit.
Nitecore is top notch all around!

Great Charger! November 21, 2018
Reviewer: Dom from Michigan  
The USM2 is as good as advertised.  The digital read out and auto adapt charging are a nice touch.  This device feels like a quality one.
