First, the included power management software doesn't work on OS X. Is it really that hard? No, it's lazy. Also, after turning on the device for more than 24 hours, the device did not immediately switch to battery when the device was turned off. There were electrical problems in my area. After the 2nd or 3rd failed switch I called Tripp Lite tech support. They were very easy to contact (on a relative scale). We have dealt with the topic. After several falls, it switched properly once. We decided to take a break in time and it worked. Within a few days, the UPS began to fail reliably. Finally came the technical support from the USA, but the block itself was made in China. This country is doomed
