I love it!! Couldn’t imagine not having it. It cuts the noise down to impressively acceptable levels, great for music venues and wineries. The quality is top notch and I’ve never had a problem with overheating. We run it in rain snow or shine! Bottom line... a great investment and I love it!

— Dia De Los Tacos. Honolulu, HI
“I knew I would need an enclosure of some kind for my generator. I had searched on the Internet for some time for a solution that would address all the concerns. I found some commercial options but the cost of enclosure was double if not triple the cost of the generator, not to mention a great big bulky box that would take up a lot of yard space. However, I was very fortunate to come across the Zombie box! Upon reading the product description and watching the online video on how this box really worked, I was blown away! Here at last was an enclosure that addressed all my needs, not over priced, and it was modular.

Rest assured, this product works as advertised. Assembling the enclosure does not take a long time. It greatly reduces the noise when the generator is in operation. The exhaust fan on top lid efficiently vents the heat to the outside and having the ability to lock it up so no one can gain access to your generator is very nice. I have no regrets purchasing this enclosure for my generator and if your situation is similar to mine, I highly recommend you do the same!”
— Gary S. Waynesboro, VA
“My neighbor bought one about a year ago.. The construction and finish is top notch. The sound is cut down by a good 75%. You can stand next to the box with the generator under load and have a normal conversation”
— Brian S. Dallas, TX
“I’ve run it in some very hot, humid, summer weather under direct sunlight . Never had an overheating issue. This is a very well designed piece of equipment. It is essential for our business to have a quiet generator. The added protection from the elements is a bonus. One of the best investments I have made for my food truck.”
