If you look closely at the guarantee you will find that there are so many ifs, ands and buts that it doesn't really cover much of anything. That aside, if you understand that these (and most Surge Protectors) will not protect you from lighting strike surges, these are a fair deal - not spectacular, but fair. They will help protect from regular power fluctuations. To get good surge protection, you need to invest in either an uninterrupted power supply unit (for other tan appliances) or a whole house surge protector installed at the main breaker box. The whole house option is probably the best, and really, it doesn't cost any more than a new fridge or other expensive electrical item.
