The tablet itself works beautifully. Because it's lightweight and has a large touch area, using it feels almost exactly like holding a pen and paper. The buttons on the side have symbols on them showing what they use, but I can't see them without turning on a desk lamp. After a day or two of use I stopped having to check what I was hitting, so that's no issue at all. The version I received has a battery powered pen, and I'm genuinely not sure if it drains while not in use but its easy enough to just remove when done using. The pen stand also comes with four extra tips, which is nice since the item description implies no spares. If you're more confident in your computer's abilities, that should be all you need to know. However, my PC does like to argue with the software so I'll detail that here: Most dramatically, if I ever forget to close the 'TabletDriver' program before unplugging the tablet, the computer starts acting like I'm pushing every key and swinging the mouse madly, which overloads the computer to the point where I can't fight it well enough to look for a fix - other than shutting down or just leaving the tablet plugged in all the time (which I do). Also, occasionally, using both mouse and tablet is a bit finicky. If you click somewhere then try to draw with the pen it will start and end about a half-inch above where you press - meaning your lines start and end with a 1/2" vertical streak. Clicking the mouse once then trying again fixes that. If the device came with no drivers at all I may have given it five stars, but the fact that my personal PC needs to be persuaded to play well with it detracts a bit.
This unit protects my desktop computer and printer. I experience one instance that it did just that. Instead of my computer and printer being zapped by what appeared to be an electric spike, the Tripp Lite tripped the room circuit breaker rather than damaging my PC and printer. Since the computer and printer stayed on I didn't lose any data nor have any damage done to them. The only negative would be that it's not easily moved because of the weight and does take up more room than a smaller less powerful unit. A small price to pay for a good product.
Everything seems to go on batteries these days. I purchased this unit about two years ago after a different battery-backup UPS system (different brand) proved inadequate. I run a Windows 7 Pro system with 2 1-TB harddrives, four 23-inch LCD monitors, two laser printers and a 15-inch MacBook Pro (with a 24-inch external monitor). All this is my workstation, my home office system, and I need it to run 24/7. I probably spent $80-$100 on this baby when I purchased it, and every time there was a thunderstorm or some summer-induced brownout, I didn't need to rush and save files and close applications because the UPS would keep my system running for 15-20 minutes. Since these were brownouts, not lasting more than 1-2 minutes, the only thing flickering were some of the monitors powering down and coming back to life. This UPS worked so well that I forgot to replace the depleted batteries a couple months ago and my Windows machine would shut down after a brownout. Buying a set of batteries is a good investment (the batteries last for 2-3 years anyway). No rocket science degree needed to install these batteries. This week, a brownout happened and the UPS just beeped to alert me of that, and I had nothing to fear.
Its a nice ups but the always on display is a eye killer at night and the software is fixed. I think they fixed the display problem in the new versions, i would check out one of them but other then the display i got no real problems with this ups.
