Definitely read some of the reviews~.
Although, like Angewin, I would avoid getting jelly toys. They reek, give off chemicals that could irritate you, and often melt with contact with other toys, especially with other jelly and silicone toys because of their chemical properties. They also yellow over time and eventually become unusable. You'll read a number of people noted that in that product as well.
If you want something similar to that product though, I'd check this out: link
It's a little bit slimmer than the Lucid Dream 14, but it is made of a safer material, namely being TPR silicone which is essentially similar to jelly, but less porous, doesn't yellow or have as strong an odor and doesn't contain potentially dangerous chemicals. It's still porous and should be contained away from other toys though to avoid disfiguring and catching lint.
Also, for that particular model, it's cheaper and safer than the Lucid, and also comes in a wide variety of colors!
