Vacuum stimulators 2023

[dreamworld]

Hello
Are there those who tried many models and said that this is the bomb or are they generally different? I’ve had a Satisfyer 1NG in my life and now it works, I’m happy with it, but it’s already 5 years old.
Satisfyer Pro+ G-Spot we tried this one, didn’t like it, although it was also advertised.
A little more on sale, Satisfyer Pro 2 Liquid Air - a new technology? Is it an advertisement or has something really changed?
In general, do they feel different in some way or are they all + the same, I don’t want to buy up the entire store to check if someone tried it and found something cool?
