"I was thrilled that the IGAN running cover fits my Westinghouse WGen11500TFc perfectly. The waterproof flaps and side covers are durable and functional. Installation was a breeze, taking less than 45 minutes without any tools. I feel the cover is great for light to moderate weather, but I'm not so sure about heavy rain."

"The cover I bought for my Generac GP9200E is just what I needed. Assembly was straightforward with clear instructions, and I appreciate how watertight it feels. It's designed well enough to let me run the generator without removing the whole cover, which is a fantastic feature!"

This cover not only protects my generator from harsh elements but also allows it to run efficiently. I believe it's a worthwhile investment that will last for years."

"I wanted to protect my generator from heavy rain, and this cover seems to be doing the job well. Although the instructions could use some improvement, it's basically a simple tent that I was able to install in under 15 minutes. However, I did notice one of the poles bent and had to patch it with duct tape. Overall, the tent material is sturdy, but I'm a bit concerned about its performance in strong winds."

"I recently covered my Champion generator with this after easy assembly. Living in the mountains, the weather can be really bad, and this cover does a fantastic job at exposing what needs to be open while covering everything else. Durable materials are used, and it has Velcro closures that finish it off. It's been a tremendous help when my generator stays outside, and it fits perfectly. Overall, it's doing exactly what it was intended to do."

"I bought this recently and I absolutely love it! It seems fairly quiet for its size, and I feel like I got a better value for around $1,100 than I would have with a $4,000 Honda. Setting it up was simple, though I wish the instructions had mentioned not to break in the motor with full synthetic oil. The push-button starter and battery worked great, and it powered my whole house, minus the central AC compressor. I also got the Champion generator cover for rain use, and it feels quite sturdy."

"I found assembling this cover to be quite straightforward. However, the mounting instructions for the clamps could have been clearer. It indicated to mount them 9 inches from the bottom of the gas tank, but it would have been helpful if it specified that meant from the top of the clamp. Overall, it seems sturdy and should provide good protection against the weather."

"I've owned my Champion generator for three years, and this cover has held up through multiple seasons while sitting outside. The fit is great, and I even pulled it over the wheels to protect them too. It works very well."

"This cover is fairly heavy-duty and stays in place even in high winds. It's much thicker than other brands I've tried. I can highly recommend it, especially for my 100520 open frame inverter model."
