    If you have a Bose Subwoofer manufactured 2006 or earlier, there’s a possibility it might ignite under rare circumstances. Bose have a recall:-

    Did I say lightning strikes? No, I said "power surges" and, yes, thanks to the many, many long-winded explanations from my EE father who worked on the electrical grounding system for the lunar module and, following that, in EMC, I know the difference (also he was living with my grandparents when their house had a direct lightning strike in 1959 and, hey, turns out the MAIN cause of damage to electronics is, uh, flooding them with water when you put the fire from the lightning out, but I digress).

    When the power goes out during an electrical storm (at least in the US, where many areas are prone to many electrical storms) from lightning affecting the power company's systems (and this can be in a number of ways, won't go into boring details, and, yes, can include a tree being hit by lightning and falling on a power line, etc. etc.), there is often a surge when the power is restored (even if it's only out for a few seconds). Can be a power surge FROM the electric company or, from all YOUR household stuff turning back on at once (AC, refrigerator, heat pumps, etc.).

    And, maybe because companies are worried about getting sued in the US, if you buy a "real" surge protector there (usually says rated for audio-visual and PCs or somesuch), they do work. No matter what electronics we had, they were UL rated and maybe some other certification stuff, my father is dead now, so can't ask him. We also had some whole-house grounding thing that I think, eventually had a ground wire run to a cast-iron waste pipe in the basement. We were a grounded family.

    No matter what the tech, no matter how young we were, my father felt we needed to know the intimate details. Thanks, Dad, for being my inspiration...to NOT major in electrical engineering and choosing materials and mechanical engineering instead.

    But I didn't think the OP was asking for the long-winded version of my answer that I have now provided. I do know that I experienced brief outages and quick restorations of power in HK during electrical storms (not as prevelant in HK as the US) I really don't know about the power grid in HK and its reliability or lack thereof. So, I just threw that in as something for OP to consider.

    I'm sorry to hear that......

    This is why I opened this thread to educate me that won't happen something like to me and to anyone else who find this thread informative.

    Thank you for the recommended brands. Obviously, I'm going to do my research as well.

    I never knew that those review websites are not that promising to trust them blindly. I used to go on those websites as well to save time in order to get a final answer on which items I should purchase. It makes sense though. On the other hand, as long as they provide solid reference, I will trust the review but not 100%.

    With something that is unbranded, there is no accountability.

    At least with something that is branded they have a reputation to uphold and they will rectify faults.

    Taking my example of Bose, they are a very respected brand. They issued a voluntary recall on their sub woofers even though their products were sold around 20 years ago.
