Awesome product selection, efficient website and ordering, and very quick shipping!

Thank you ACF!

Works great and last a long time. Keeps the greenhouse cooler automatically. Been using them for years.

The Bayliss MK7 power tube works great. I ordered two for my greenhouse. They are very easy to install. If you ordered these then you must order the Replacement Spacer Set. Shipping was fast too!

I recently purchased replacement tubes for my two existing greenhouse openers. They arrived quickly and were easy to install especially with the enclosed directions, except I lost one of the 2 special washers included and had to call for a replacement. They were most responsive in quickly mailing a replacement. Suggestion: ask for 4 washers to cover any mishaps.

The vent power tubes were overdue for replacement. The new ones are easy to install. Highly impressive was the very rapid shipping from the east coast to California, even the second time I ordered, after discovering I had ordered one too few.
