This toy is considered a luxury toy. It's fully waterproof, rechargeable, quiet, and wireless. I personally don't own this toy so I can't really tell you any details of my own experience but you should check out the reviews on it which you can find here: link There are 4 reviews in total and that should help answer your question. I presume the quality is good. Lelo makes excellent toys. Good luck!
The quality! In my opniion, these are the best made sex toys on the market. They also have a year warranty and 10 year guarentee. Yes, they are an investment but when you consider the cost of batteries and replacing an inferior toy several times, it's really not as expensive as you'd think.
All of Lelo's products are higher priced. They're good products and come with a warranty. If you can find the Tiani 2 anywhere, it's definitely worth the price. I'd like a second one, but Lelo no longer sells it in the US.
