If you read certain reviews you will see that some people mention a bubbling problem with the silicone. Some have it, some don't. It is a great toy to own and should anything happen within EF's return policy time frame, then you can send it back for a replacement if you get one that has that problem.

I have the second generation and I love it. It's basically the same thing except it has 3 buttons instead of two and the bubbling issue was supposed to be completely eliminated.

I've had mine for over a year and it's still going strong. I've never had any problems with pushing the buttons (maybe because I have short nails) and I've never experienced the bubbling either, and I use it for long sessions.

what does that mean, bubbling? That sounds...gross.

The silicone is free from the core and the air inside the toy heats up and expands.

The Leaf toys have the exact same thing. It's because they're waterproof.

I don't know how they would "solve" that unless they took away complete waterproofing to allow a vent for the hot air. People have solved this with a tiny pin-hole, so if someone's *doesn't* do this, then they have a "leak" in the waterproofing at least that size to allow air-flow. I doubt it would compromise waterproofing to a huge extent, so they can probably still label it as such if that's the case.

It's not gross, it's just a physical property of hot air. :/

I wouldn't return the toy because of this, it's not really a defect and you're likely going to get a toy that does the same thing. I guess it just feels like a waste to me since the toy can't be re-sold and nothing was wrong with it.

I've had mine since late November I think, and I still love mine! It still works great!
