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 have a couple very old 1500 cyber power that I am able to mute.
Edit: yes you can according to the manual: https://www.bhphotovide

I just want to use this for the cable modem and my router. How many hours will this give me in the event of a power shut off?

This is much more efficient than the 12V (or 24V) DC --->120V AC -->12V / 19.5V DC procedure and saved a UPS.

Or in my case, my power almost exclusively goes out for a second and then comes back, and these allow me to keep my internet and PC uninterrupted while I'm working.

cases AVR is more important than pure sine wave. keeping that voltage steady is more important than a step or a sine wave voltage drops are the leading killer of electronic equipment. in short you want a steady voltage at all times coming out of your UPS so in a sense it's actually a voltage regulation system for sensitive electronics that don't like 1
0 or 15 volt swings

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
