I just received this inverter and I thought it was great. Although I have not used it yet, at first glance it is easy to see that it has been designed with high quality standards. Just look at its strong battery connection cables, very elastic copper terminals. Its AC and DC inputs and output are very robust and super quiet. I have used inverters for years but so far in Design, Packaging, and performance it is the best I have had, we will see in time how it turns out, I will tell you later!
