Not hard to assemble but one leg of the unit was not manufactured properly, causing great difficulty and delay. I had to file down this defect in order to finish the assembly.

My husband is an accomplished "DIY" person and still it was a bit of a challenge to get together single-handedly. As far as "tumbling" goes, once it gets a decent amount in the bin it's a beast to spin; I think that may be due to the boxy design. We still do not have a load of compost completed (it has only been 4-6 weeks) so I cannot yet comment on that aspect of it. I do like that my stinky 'garbage' is now contained, and the tumblers aren't an eyesore like my open bin was, so in that respect I'm happy with it. The true test will be if it effectively yields lovely "black gold" as the end result. :)

Good compost bins. The assembly takes considerably longer than expected, but once that arduous task is complete they work very well

[This review was collected as part of a promotion.] I purchased this composter few years ago and had difficult time to put it together, way too complicated and some parts seem to be low quality which are already breaking. From my personal experience I found this composter poorly designed and very difficult to put together with a short time life quality.

A LIFETIME closed composting tumbler is the best way to compost. I don’t like open composting, turning compost with a pitchfork or shovel, because that stirs up too much dust and mold that gets into your respiratory system and onto your hair and clothes. Open composting also attracts rodents. Closed tumbler composting works faster, and having a double closed tumbling composter allows you to fill the second one while the first one is completing its processing. I enjoy bringing kitchen peelings out to my composters almost daily. It gets me outside to look at nature. It’s fascinating to see the breakdown process that results in wonderfully rich earthy compost to add to my garden. LIFETIME guarantees their products for life, and you can rely on them to follow through if there are any manufacturing defects. Lifetime is excellence! They quickly responded when I needed to replace the frozen rusty inside latches. I think they have redesigned the doors from hinged to sliders, which appear to be a better design that won’t rust. I’ve had this LIFETIME double tumbler for around 15 to 20 years and it’s sturdy. I also have a larger single LIFETIME tumbler for over 20 years that came with outside latches that seem to be good quality stainless steel, and so this tumbler with the stainless steel outside latches is a great design!

We bought one composter and liked it so much we purchased another one the following year. It has a large opening that ensures it is easy to get the compost materials in and out of the container. It is large enough for the contents to heat up but still small enough to turn easily. Living in a high-altitude, zone 3 area (aka. cold), we are usually able to empty 3 of our compost barrels in the fall and the fourth in the spring. An added bonus is that this composter doesn't attract rodents.

We purchased at Costco several years ago. Unit does an outstanding job of composting however some of the metal parts have rusted to the point that one side is no longer usable. Called customer service to see what I could do to save the unit and they agreed to send all of the rusted parts. Unit is great...customer service is excellent.

I too had the interior hardware rust on my double rotating compost bin. I was on the phone with the Lifetime customer service representative and he kindly, and quickly agreed to send me all the parts I need to replace the hardware free of charge! It was a great interaction in this day and time where customer service seems to be almost non- exsistent. Thank you!!

I have had my double tumbler for years now. It has been perfect for our family, and I can't even believe how it has reduces our waste going to the landfill. The inside mechanism rusted, and they sent me brand new parts at no charge. It took a little to get the rusted parts off the unit, but all is well and we are back in business. I think this is a great product.

Love my double composter and the customer service at lifetime is excellent. A live person answers the phone and are very knowledgable regarding the parts or information about the LIFETIME products. I recommend LIFETIME the support is there after the purchase.
