Like others have said, very annoying to install in small spaces. If you have small hands like me you can fit them through the side panels to tighten the toilet screws. We had some technical issues regarding our plumbing, 
but totally not the toilet's fault (just the lazy homeowners before us). Other than that,  functions great, looks sleek, and most importantly is easy to clean.  4/5 only because it's a tight squeeze to install, still would buy again.
