Top critical review
Did what it's supposed to, but RIP. Bits of caution advised too.

I bought one about two months ago, moved to a new flat last week and there were some voltage fluctuation issues, one night things got out of hand and the surge lasted for quite a bit (NEVER ignore even the small electrical issues, i have gotten the wiring system checked since). I had my office laptop connected to this surge protector and all off a sudden i hear a pop and then some fumes coming out of the first socket that's closer to the switch. My room MCB immediately went out and i disconnected the device from the wall socket. The surge protector was gone, but my laptop got saved along with the charging cable (so the knight did its job).
I might go for another one, but i am doubtful of what happens in a scenario when I'm not home and this thing happens to blow out with that little flame once again? (the knight's got a scary blade!)
Also, these protectors aren't fuse based, their lifetime depends on the Joule rating (that means they might handle one big surge or multiple small surges depending on the scenario- their MOVs burn out after repeated power surges, so eventually the surge protector starts functioning as a power strip). Also the energy adsorption rating for this (1000 Joules) is better than the Belkin ones (200- 420 Joules).
I will be opening it up once i can find my tool kit in the packed boxes, and might edit this review if the electrical anatomy reveals anything interesting.
The USB ports are okay, only issue is it heats up a slight bit around that end when you charge devices like power banks for longer durations.
tl;dr- Does exactly what its meant to do, slight caution advised as i saw some flames when it blew up.
