Very good!!

Ordering was easy. Got what I ordered at a fair price. Used the chat function to get an ETA on my package and they helped me quick and were responsive.

good price.

Service was great. However, I first needed to change an order & found I had to cancel it and reorder correctly. I did this. However, the second order was also cancelled by the warehouse because they thought it was a duplicate. I reordered again! The battery was shipped this Monday & arrived Tuesday! So... other than the "safe" second cancellation, everything is 100% good! Battery arrived and I did a quick voltage test. 12.78 V ...

The order got here later then it should have because I paid for faster shipping. Other then that everything looks good.
