QA issue - but easily resolved.

Upon arrival I tested it on 3x 18650s. Push the spring-loaded arms down to insert each battery, and with the third arm down, the back cover popped out.

Excellent charger, very good workmanship, long service life!

Update 12/30/2020: It has been almost two years since I use this charger 4-5 times a week and it still works like new! I've charged every type and size of battery it can charge and never had any problems.

Original review 02/21/2019: This one has a lot of features for the price. This is an excellent charger that will charge batteries…
