Bests & Worsts Reviews from Amazon

I rarely write Amazon reviews, but in this case I was totally disgusted by the lack of customer service for existing customers. Although cyberpower UPS units are cheaper in general than APC, I've found that cyberpower will not stand behind their products. When the battery went dead on this unit I removed it and tried to find a replacement, only to find they are priced around 2/3 or more of buying a whole new unit. When I emailed cyberpower about this I got a reply from tech support saying this wasn't a "user-serviceable" battery. I then asked if they had a pro-rated replacement for existing customers. The reply I got was very dismissive and basically ended with the equivalent of "tough luck". Following is the last reply from them: "The unit has a torx security screw holding the compartment in place. Some users have discovered what size torx head this uses and have been able to upgrade their own batteries, but unfortunately, I am unable to assist with that. Unfortunately, we do not have any sort of upgrade program. Thanks, and have a great day!" Yeah, thanks a lot. I tried this UPS because it was cheaper, but I don't feel it's worth it if you have to buy a new one when the battery dies. I'll go back to buying APC units, since I've never had a problem getting a reasonably priced replacement battery. Buy at your own risk.
