Recently purchased unit online, what was advertised as an excellent condition used Multiplus 12V -> 120V 3000VA unit. It arrived with a dent in the left side (when viewing it from the front cover), where the two bolts are that hold (what I assume is a giant transformer inside.) Should I return to seller or is this mostly cosmetic? With the front cover off it appears in excellent condition otherwise.
Any advice would be helpful.
Thanks,
