great size for me and really locks in place, could have a more ergonomic base but not uncomfortable.
bigger than it looks-but easy to use-good quality, probably not 'beginner' level though.
I read a lot of overseas reviews of this before I went for it. negative comments were; "too difficult and floppy to insert"-no, its easy with lube and the valve open, they may have improved the design as it has afirm inner tubei; "the flange is too small, won't stop going inside completely"-yes it is a bit too small, up to 5 pumps I found it sat well but did slide in and allow some leakage upto about 10 pumps (15 pumps and you'll be too distracted anyway lol) I slipped a silicon collar I had onto it as a backup-worked well then; "poor quality-esp glue lines"-no, I inspected it closely, mine's fine. By far, most comments were positive, with great results-I agree, it's bigger than it looks and gets REALLY big :) it will fill you up even if not using it for enemas. I'm loving it
