Although I have no previous experience of the brand or model, here are some factors to consider:
- Battery capacity is way oversized for a single computer (with some accessories).
- Doesn't seem to support network connectivity, e.g. will become dependent on the one computer with the USB connection to remotely shut down any other computers in case of power outage.
- Noise levels at 45 dB is quite high (100% increase for every 3 dB - compare APC unit 41 dB)
- Replacement battery availability in 3-4 years, etc.
However as long as it has all the features you're looking for, and the price is right, then why not-!?
