The charger feels very solid and well made which inspires confidence that it will last a good while. The display gives all the information you could possibly want. It will charge just about any size and type of cylindrical battery including 21700's. The only negative thing I can think of is when charging four cells the charge rate drops to 375 mA which I would like to see higher. All in all it is a very good charger for the money.

Not as well designed as it should be - good display & solid construction except for battery holders. These are sliding/spring loaded and fiddly to get a good connection on smaller AAA batteries. They are OK only for AA, 18650 and similar sized batteries. Also the fixed +ve electrodes are too recessed/low for C batteries which it claims to charge. I could only find one slot which didn't slip off the +ve end. Tried charging two C batteries next to each other and there isn't enough room - they just don't fit. You cannot charge more than one C at a time. So the battery loading compartment needs a re-design so that the individual insertion slots are a bit larger and positively grip larger and smaller batteries than AA and the +ve electrodes need to be larger, also spring-loaded and more accessible. I always end up asking the same thing - did the designers actually spend some hours themselves manually inserting and charging AAA and C batteries? If they had, maybe the product would have been much better.Read full review

This is the best of the chargers in the price range in my opinion. The display is large and clear and more importantly accurate. As I only charge my batteries to 4.12 v in order to substantially increase their lifespan an accurate display is essential. PS: despite the size of the batteries compatible this charger does accept 21700

Great charger, which I used for 18650 batteries for a spotlight lamp. Worked brilliant for just over a year, and couldn’t fault it during that time, but a little disappointed when it gave out a loud bang and stopped working today. Opened it up, and can see a blown capacitor and a chip with a hole burnt in it. I’m impressed by the charger generally and they do have a good reputation, so I’ve purchased another one today. Let’s hope it lasts a bit longer, and the old one was a ‘one off’.

This charger works great with 18650 batteries, which have become the primary source of power in my Arduino based projects. The large display give you a clear indication of how the charging process is proceeding in a particular battery cell of interest. The batteries appear to charge quickly, so it's effectively made my dual charger redundant.
