Great investment

a month ago
Replacing an 18 year old whole home generator. A big investment, but worry-free for any basement flooding during a power outage amongst other scenarios that can and have been avoided in the past. Metro Electric from Romeo, Michigan did a great job on the install!

Yes, I recommend this product.

Buyer's remorse

4 months ago
When it works it is great, but it does not work consistently when needed. Red light keeps coming on and I question the decision to purchase this. No sooner did I get it paid off all my problems started and I have been dealing with gremlins ever since. Really do your research to make sure this brand is what you want.

No, I do not recommend this product.
