Purchased a Univent / Ventomax Replacement Power Tube on March 8. On March 29 the tube burst and is unusable.

ACF Greenhouses: I'm sorry your power tube stopped working. We will have a replacement shipped out to you right away!

In the past I have purchased whole unit. Didn’t realize I could just buy the part. Installation was easy!

Had to replace an automatic opener on my dome greenhouse, and this part did the trick.

Item was a perfect fit; works exactly as it should.

When putting up our greenhouse, a friend forced open the Univent. In doing so he broke the piston. It was nice to know that they carried a replacement part, and I didn’t have to order the whole vent again. I did not ask them to replace it since it was totally our fault it broke. The part came on just two days.
