This is the 2nd one I’ve owned
The first one lasted 22 years and I was still able to sell it to someone else. I’ve seen negative reviews about this product that I can tell you from experience are all attributed to operator errors. Read the directions and you’ll be fine. All compost toilets take maintenance. I use this in an airbnb and people are very impressed with it. No complaints. (Verified HomeDepot.com review)

toilet works great, unfortunately HD does not stock the compost and it takes two weeks to get it. (Verified Home Depot Canada review)
Friends and family are amazed at how well it works.
(Verified purchase) We installed our Sun-Mar Excel during our summer holidays in July 2001. It has become a conversational piece.
We cringed for years just at the thought of going/using the old outhouse at our family cabin site.
Then we were introduced, by a neighboring cabin owner, to the Sun-Mar composter toilet. After using the Excel composter, we consider it the most practical investment we could have made. The most surprising element – total lack of any offensive odors.
We are very happy with the product.
We installed our Excel Electric in the Spring. At our cabin we have greywater disposal, but not sewer. We have a lot of guests on weekends, so we try to all use the “indoor” toilet (the composting toilet) on rainy days, or at night… and we use our outhouse when we are outside anyway. I found the job of emptying the toilet this Spring not bad at all, the dirt looked like top soil, no evidence of toilet paper or anything.
