The primary drawbacks in reality are that the PSU may run less efficiently and generate somewhat more heat. However, in a situation where you'd want a relatively low-capacity UPS like this, it's probably to have time to save your work and shut down or you expect the power will come back in <5min, in which case the efficiency loss is likely to make a big difference.
In other words: I'd be more worried about a power surge or sudden loss of power causing damage to your computer than I would be about a simulated sine wave.
That said: this does not extend to all devices! If you're thinking of putting HiFi audio equipment, machinery, medical devices, or, like, a PDP-11 behind a simulated sine wave UPS: don't.

I don't use mine as a battery backup except on my router modem VOIP system-these UPSs are more for power conditioning and I would worry more about voltage drops than the step wave versus sine wave. For the same price if you look cyberpower sells a good sine wave UPS
