This was super easy to assemble excepting the center divider. I attempted to install it after the 4th panel was installed. I rotated the divider into ever position and it did not accurately seat in the groove in any of the positions. SO, I gave up, installed it the best i could, and moved on. If my Red Wigglers migrate from one side to the other...so be it. I'll sort them out when I sift the composted product. I think it will be be a good companion to my 150-gallon tumbler. I may use this to make starter compost to move to the larger tumbler to kick it off. I still believe that it was worth the $99 price. Thanks for keeping me informed of the shipping progress. Will buy from you again if the need arises.
