The Leo is made of silicone, and has a plastic base. It has no noticeable smell to it, and is very smooth. The insertable part is not sticky or tacky in any way. The tip, with its lion like features adds some interesting texture to the toy when inserting, but otherwise it's just smooth to the touch.
The Astrovibes leo is a nice standard dildo. It's a nice size, not too thick, not too short, and the lion-like features at the tip add a bit extra for those zodiac lovers. The lion look is nice, but it's not a very discreet toy. For travel, remove the batteries, so nothing rubs it and turns the vibes on.
As far as the vibes go on the Leo, you couldn't get simpler. There is one red plastic knob at the end. Turning it turns it on and increases the power. There are no other buttons or dials to bother with. It's a little noisy at the highest setting, but on low it's not loud at all. While a little more variety in vibrations would be nice, if you're just looking for a nice standard vibe, this one does the job.
Because of the smooth surface, this Astrovibe is pretty easy to clean. The toy is not waterproof, though, so when washing it with warm water and soap, watch out for the twist nob at the end. Like most silicone toys, it does have a tendency to collect hairs, but wrapped in an old shirt or something makes it easy to store. Because the toy is mostly silicone, do not use silicone lube with it, as it will make the toy tacky.
