5 of 5 Well built item March 31, 2018
Reviewer: Michael Walker from Willington, CT United States  
This is the solution to keeping my generator dry when I’m running it outside. Easy to assemble, even with the slight modifications needed for my particular generator. Haven’t had the opportunity to try it in rain or snow but the coverage it affords looks like it will keep it bone dry.

5 of 5 Its worth it. December 18, 2017
Reviewer: Michael Sileo from Rice, Virginia  
My original package had no assembly manual so putting this thing together was a battle of extreme frustration.  CSR provided a PDF file in an email and after looking at the pictures, it took me a total of 20 minutes to take it apart and reassemble it correctly.  Aside from the fasteners there are no metal parts.  The tent frame rods appear to be fiberglass, smooth finish.  The clear plastic shielding for your battery and charging panel are quite thick.  In addition to the tent I also got the skirt as I am using this as a permanent enclosure for the 15 KW generator.  The material is heavy duty and the whole thing hold together with Velcro strips, so easily attached and removed.

Given the value of any generator the cost to protect it is insignificant.  Mr Carpenter assured me that they would check all packages to make sure the manual was, in fact, included and he is sending me a hard copy via US Mail.

Thanks Mark and Merry Christmas to you and your team.

Reviewer: Anonymous Person from JACKSONVILLE, FL United States  
Appears to be a well designed product.  Still awaiting delivery of back ordered generator so haven't been able to trial fit but am sure it will do everything it is designed to do.
