Any Experience with Chargery BMS?

 I’ve been considering this battery management system for a while for my Nissan Leaf batteries. The specs look impressive, it’s relatively inexpensive, has a display. It monitors temperature, amperage, and voltage.  But it’s not from USA or Europe. 
 Is it too good to be true. I read a while back that they fixed a few bugs in the new model.

 This business has been selling them on eBay for a while. They are in AZ. I may wait until I get to AZ then buy directly.  And also buy some solar panels directly from Santan Solar to save on the shipping.

Now Chargery has a dual AC/DC input balance charger.

These chargers look very useful as they are programmable,...blah blah (insert lots of texhnojargon). 
 I guess I’ll be the product tester and reviewer for the group and try one of these units.

I checked and Electrodacus has a new BMS. Has anyone tried it? Thanks
