I have 5 Sil-a-Gel toys (all Doc Johnson brand). If you're looking to buy something that's a reasonable price but is also of good quality, you can't do much better. I would definitely recommend it over jelly or even rubber toys, since Sil-a-Gel is easier to maintain and is less likely to cause an allergic reaction. [[Everyone is different, however, so it may still cause irritation in some.]] Sil-a-Gel also has mild antibacterial properties to reduce the risk of infections, unlike jelly and rubber.

They can't be shared or used in multiple orifices unless you use a condom, since the material cannot be sterilized (i.e. boiling for 3 minutes, throwing it in the top rack of the dishwasher, or washing in a 10% bleach solution).

The one thing I don't like about Sil-a-gel is the smell. All of my toys were scented in some way (lavender, cherry, blueberry) to cover up any rubber odor. I was able to get past the smell with frequent washings in warm water and mild antibacterial hand soap, but that's just me. A lot of people don't like having to air out their toys for a week or two before the odor fades. This is understandable, since the smell can easily fill a room (it smells more of the added scent than of rubber, but it's pretty strong nonetheless).

It's kind of sticky, too, so you have to keep it in a plastic bag or its original packaging to keep it from attracting too much fuzz and hair.

I think I covered everything, but let me know if you have any other questions!
