Unfortunately, the item I received was used and damaged, rather than the new condition advertised. However, the customer service team was great and corrected the issue. Even with some holiday delays in communication, I am very satisfied with the final resolution.
Item as described. Seller shipped quickly. Trucking Co. a little slow. Very ell packed. Communications with seller excellent. Thanks.
Item was shipped from CA to Florida in 3 days. Packaged very well. Awesome seller.
Great product. The product arrived brand new and packaged well. Best price on a quality power inverter that I could find online. The inverter has an aesthetically pleasing color and design to look at. Thanks for the great customer support after sale also to answer any and all questions I had. I’ve never had a company reply and reach out as much as they have. They have won me as a permanent customer of solely their products.
Order delivered on time with no issues
