Opti-UPS ES1000C-RM 1000VA 700W 1050JOULES Automatic Voltage Regulator AVR 8 Outlets RJ11 RJ45 Software Cable

I have had three of these units for a number of years and had no problems. One unit failed and was out of warranty. Since this USP is well priced I figured it was better to purchase a new one rather than spend shipping and repair costs on a 4+ year old unit. Well, the new unit failed within 24 hours and Amazon quickly shipped a replacement unit. I installed the replacement unit and powered it up. All was looking good, less than an hour later the unit failed. I powered it back on, and it shunt down in less than 5 minutes, powered on again, same thing. Requested another replacement and got an email back from Amazon indicating they would not attempt to replace it again and would be refunding the purchase price one the defective units were received. Not sure why Amazon would not replace it a second time. Other than that, they were great. In any case, very disappointed with the UPS even though I had good luck with these units in the past.

I noticed there were no positive reviews on Amazon for this UPS and felt bad that I had been running mine since 2009 and had never submitted a review. I have replaced the batteries once but apart form that love these UPS's. I have the rackmount and the stand alone. I have never had any problems with them other than having to switch the batteries. Great product and not a bad price.

I have had this model and the previous model, both have been running for many years. Keep in mind the batteries in the unit are the same as car batteries but smaller. After a few years they need to be replaced like any other battery. Maintain the batteries and the unit will serve well.
