While this attachment is not a necessity, it does raise the toilet quite significantly. I could see this being useful for taller individuals.
I can’t comment on longevity or build quality seeing as it just arrived but it looks and feels quite frankly “cheap”.
You also can not simply insert the toilet into the mold without taking off the tin sheet where the battery is located at the bottom of the toilet. This is slight a nuisance. Nothing I’ve read regarding this product mentioned having to remove a piece of the toilet.
Will update my review if any issues arise.
