Inverters - Poor products with even worse service

Terrible products and very poor support. Do not purchase an inverter from this business, you will certainly regret it. I am now on my third inverter from Geewiz that has stopped working within a few months. Upgraded to the Lithium pack with pure sine wave inverter after the lead acid ones failed. This product turned out to be even worse. The support service is poor, response times are slow and any urgency is lacking.
