We really have only just one downside of Observe for this unit: its high price. This is often the most expensive device on this list and it is the highest-end UPS accessible to individuals. In case you have genuinely high-stop hardware, though, That is value each penny. What is an additional ~$a hundred and seventy to protect $1,000+ in hardware?
