So far working very well..
I have not had this for too long yet but will update accordingly.  So far everything has worked up to my expectations.  The battery quality looks good and every battery is responding well so far.  I installed 8 of these in parallel for a solar system, and they are charging and discharging very well so far.  The experience with the seller and shipping were very good too.  I recommend it.
