This is one of those "insurance" things. If it works as it should you will never know.
You don't have to be an electrician to install this but if you are electrically challenged be safe and hire an electrician. It should take them less than an hour to install.
For a long time I have had plugin UPSs or protected power strips for sensitive electronics, but now I live in a place prone to power irregularities. My local power utility will install a whole house protector for a cost of $10 per month added to the electric bill. At that rate the Leviton protector will pay for itself in about 18 months. I am happy to have installed this unit to protect the rest of my electrical devices and appliances from surges. I especially like the indicator lights that show that the suppressor is in good working order.
It was a breeze to install; it took me less than 30 minutes from power cut to power restore, and that includes time for opening the panel knockouts and mounting the Leviton protector to the wall. If you are comfortable working around electricity you can quite easily do this yourself. You can find detailed installation instructions on the Leviton website if you need to assess the complexity of installing before buying.
Just note that this protector does not come with the four wires required to connect it to the main panel. It needs two black wires (one for each of the two hot electric busses), one white one (for the neutral connection) and one green (for the ground connection). You can use any cable or wires with a minimum of 12 gauge if connected to a 20 amp breaker. I used an offset nipple between the panel and the protector, and this worked very well for my situation as my electrical panel is surface mounted, not recessed.
