I was in the store that told it was their #1 seller. I said I need something that is going to make less work for my wrist/hand to use on my husband. First time ever purchasing this type of toy without him. I immediately thought by the look of it that It was mechanical looking and bulky.. I was assured it was the most popular stroker so I bought it. Tried it out that eve. First I couldn't even grip it with 1 hand. It was too big for me to hold. We used waterbased lube but he said it felt cold and texturless. The faster I went the more lube was needed and the tip just popped out with no stimulation. On top of that it was not visually stimulating. Men need tight warm, snug visually stimulating and wet non messy strokes. This was neither of that. . I had to work harder and longer, mind you my husband is pretty large and thick but this still was even too loose for him. After finally achieving the cleaning process was not very easy either. I gave it 2 rate only because despite my husband telling me to toss it and use my hand I used both and achieved because I spent the money & was being stubborn. Thumbs down
