Yes, they are reliable. I used to be a Fleshlight user, but this thing is on another level. You can’t beat the feel of a real woman and this doll is very close to the real thing. I have had full size sex dolls but they are very heavy and hard to position. This doll is very easy to hold and move around without feeling tired. It is also very easy to clean and very affordable. This is a great doll for beginners. You did a great job on this doll.
