I don't think theres anything we haven't thought of LOL. I have seen it all after seeing some of the toys on this site. Its insane. I would REALLY like the prices to go down LOL...Would that be "making them better"? LOL
Yes! Seriously! I'm really tired of seeing so many vibes gendered feminine without giving other color options.
I'm also shocked that adjustability hasn't caught on more--bendable g-spotters (like G-Ki) and rabbits with adjustable clit vibes.
Battery-operated vibes would be SO MUCH BETTER if they were engineered to work with rechargeable batteries. They're made to work with carbon batteries (your standard disposable Duracells or whatever), so some of them run really pitifully on rechargeable batteries.
A wider range of colors would be lovely. I've got nothing against pink and purple, and my favorite color (blue) is somewhat common, but it'd still be neat if there were more colors to suit everyone's tastes.
And waterproofing should be the standard for most toys! I let loose fluid just about any time I use a vibe, so I prefer to use buzzy toys in the shower. I've turned down a lot of toys simply because they weren't waterproof (or at least splashproof). At least it's becoming more common.
