Like I said before, this isn't a high class, lifetime quality toy. The screw on base is a little iffy, it is waterproof, but I'm not sure total submerging for more than a few seconds wouldn't do it in. The material frays a bit where the toy meets the plastic screw on base, that controls the gradual speed and untwists to open the battery compartment.
The size is very moderate, you'd have to be very very small to find the size uncomfortable. There is a lot of give to the TPR material as well, so as far as size is concerned, unless you dislike smaller sizes, you don't really have much to worry about. The problem with rabbits is always size, getting the clit stimulator to reach, etc. The bendability takes some of the guess work out, because you can bend the base up to better reach your clit.
Also, the Nestlin' Bunny, not a very discreet toy. It's a pink, 9 1/2 inch long rabbit vibe. And you should definitely take the batteries out when not in use. Not to protect the toy, but to keep it quiet, the slightest shuffle in the wrong direction will set it to buzzing, and not very quietly. When actually in use, the sound is muffled some. But, if the bullet in the bunny gets pressed wrong, I think it hits the battery or something hard, because it then creates a "Wuzzzezzz" sound that isn't only distracting, but quite loud.
