What people saying about the Yielder Max – 26 Plant - Grow Box

"I did a lot of research before I chose the Yielder Max. All the publicity looked great so I decided to go with it. There was an initial issue with parts being out of stock, but communications from the company were excellent. I was kept updated at all times and when the item finally shipped tracking information was provided and I felt in safe hands. When the Yielder Max finally arrived I was very happy. Packaging was discreet and very thorough, the whole unit being palletized. Once unpacked we found everything in order, exactly as it should be. Set up was very simple using the manual and I had the unit up and running in around an hour. I checked the machine and it is light tight and totally silent. Still need to check the odor as my first grow has not yet come to fruition. However I have total faith in this item. Customer service is superb and I am confident that I will get back up if I need it. So far my experience with this company has been very satisfactory and I would recommend this system to anybody."
