The inverter works great! Easy to install, efficient, and reliable. There was a small issue with the delivery, but Cassie was quick to assist and resolved it right away. Overall, great product and excellent customer service. 

Delivery： The delivery was fast because unlike most on alibaba this item was shipped 1-2 days Quality：This quality was very good  Design： The design was very good  Service： The service was excellent, they uploaded all the tracking without you having to ask, and not change the price of the item like most try to do on alibaba. Excellent seller unlike the rest on alibaba. I will buy again from this vendor.
