Very easy to setup and work perfectly with Bluray drive
Easy to setup and perfectly compatible with both DVD and Bluray drive, speed is at the top, physical size is compacted. If you are going to reuse an old optical drive from laptop, this is the one to choose.

Very solid build and works perfectly with 18650 batteries.
Have all the features I need, night mode is super convenient when you need charge the batteries overnight. The only thing I am not sure is the thermal detection, one of my batteries is faulty and getting really hot when charging but I am not sure D4 can detect the thermal and stop the charging or not. So far no explosion and I am happy.

Simple the best
