Pruchased 2 since I have 2 panels. Breakers arrived when expected. easy to install. So easy I went ahead a installed a couple more for a friend.
took 10-15 minutes to complete 2 panels. I won't know how well they work until the next lightning strike. Last lightning strike cost me several thousand dollars. Hopefully these will help.

Pretty sure it saved us from a lot of damage
South Florida. Had lightning strike my power pole this afternoon. So far I've discovered it blew out a power supply for my modem and an LED light fixture in the garage.
I installed one of these SPDs last summer. It's cheap. It's easy to install if you have a little knowledge on residential electrical hardware.
As title suggests, I think it saved us from a lot more damage. There's no way to know for sure, but I'm pretty confident it's true.
Best part - the SPD is still alive in my panel.

I installed one of these in my load center and another in my in-laws. It's easy to install and provides surge protection for your entire home. Just make sure you install it in the first two breaker slots so the surge is diverted to ground before it reaches any of the other circuits.

Easy Install for great protection
I don't know why the stores don't keep these in stock. They are an easily installed option for whole house protection. It literally took less than 10 minutes and that included moving the stove breaker so I could place this near the feed. Make sure you have the right type (QO) breaker panel. Turn off the main. Snap it in. Turn on the main. DONE!

The directions state that the preferred location is at the top of one of the banks of circuit breakers so if necessary move two down (obviously after turning all breakers off, then shutting off the main breaker).
Then reverse the process, turning the main breaker on then flipping each breaker on one at a time until all are on.
I had one nearby lightning hit that may have caused a surge and damaged electronics and appliances. This surge protector appeared to work perfectly, turning off everything momentarily and back on in an instant.
It also looks cool and finishes off a perfect panel installation. A must have for a new Square D QO 200 amp panel.

Simple - Peace of Mind
Very easy to install. If you are comfortable installing a breaker, you can easily install this whole house surge protector. It took about 15 minutes to install. I had to move two breakers down the panel so that it could be as close to ground as possible.
Given the number of computers and electronic appliances (fridge, stove, microwave, water heater, dishwasher, furnace) installing a whole house surge protector is a lot cheaper than replacing appliances or having them repaired.
(Note, I still have my surge suppressor strips in place ... just in case.)
