They lie to you about their return policies. I was new in town and trusted Apex to be reputable. the woman who sold me a cartridge was friendly enough and explained for whatever reason if I was unsatisfied to bring it back for a refund. well two days later I come back as it is not working with my battery and the extremely rude and unprofessional man who helped us told us he could not return it. we told him we were never told there were stipulations and he stubbornly stood his ground, and further added insult to injury by making us feel like we were lying to him by testing the cart outside the front door with their own battery (one, of course it'll work with your battery, and two, illegal much? subjecting your customers to this activity should be punishable by fine). after even barely getting anything out of the cart they wouldn't take it back, even after I offered to use my own battery to test it out. one of the worst customer service experiences I've ever had. you all are liars and cheats. DO NOT GO HERE. THEY ALSO DELETE YOUR REVIEWS I HAD TO REWRITE THIS ONE BC MY OTHER ONE WAS REMOVED.
