Awesome shopping experience

It was a smooth transaction from start to finish!!!! I received my item within a week. I bought an extra smart battery for my Delta 2 came well packaged. I have not tested it yet as I have had back surgery. I saved money by buying it here and look forward to doing more business with them.

Great price and works like it should!

Nothing fancy but does exactly what it is supposed to. Doubled my capacity of my Delta 2 and allowed me to run an espresso machine at a farmers market for over 4 hours.
