Take a look at the electrical damage guarantee. It might be the deciding factor for you because you get reimbursed for damaged equipment.
The problem is that will not apply to outside the US, even if the company is a US one, I don't think their guarantee applies when you ship the gear overseas.
Other problem is normally weight. As they are ship via air, its pretty expensive $$$. But I don't think there is a way around that. I could not find anything related UPS that doesn't weight a ton...even small ones have hefty pounds to them.
But I will take it as an investment, I prefer to pay good APC that will costs me 4 times the cost once they are shipped as this crap China UPS. Sorry Chinese friends, but thats a fact.
Many UPS and Battery backup/surge protectors get out of the warranty, even if your equipment fries, because the outlet that the unit was plugged into was not properly grounded.
I know here in the states, I can buy an outlet tester for under $20 at most hardware stores, and it will tell me whether the polarity and ground is correct on the outlet.
If your stuff isn't properly grounded, even a surge protector can't protect against a lighting strike.
If you've had more than 1 of these in the past 2-3 years, and the lightning is hitting your building, I'd also look at getting an electrical contractor to install a proper lightning rod and ground for the whole building.
