About Mantis

Over 40 years ago, Mantis introduced an innovative product that would revolutionize gardening around the world – the Mantis Tiller/Cultivator; part of the Mantis lawn and garden product family. Before that time, garden tillers were big, bulky, heavy pieces of equipment, and tilling was not easy. Once it was demonstrated just how powerful and versatile this new Mantis Tiller was, even the most skeptical gardeners were won over. The Mantis Tiller made tilling and cultivating accessible to millions of people who were unwilling or unable to tangle with old, behemoth rototillers.

VERY DISAPPOINTED

VERY DISAPPOINTED
I bought this in May. I was looking forward to using it. It is now September. It has been 4 months and the sides are already breaking. I took these pictures at the end of August. Just now getting to this review. I have used it successfully for 1 full composting cycle, about 2-3 months. After I used all the compost out of the 1st cycle, when I went to use it again for a new application of food scraps and waste, I noticed the sides were breaking after about 2 weeks. I am aware of the gallon size and how much to put in. I am disappointed in the life span of this bin. I really liked it, but it does not compare to the Lifetime bin with metal latches and hinges. please see pics after 3-4 month of use. I did get great compost out of it, but to pay money for only a 1 time use is now, not worth the money spent. I would NOT recommend this if you want it to last longer than 3 months.
