Robot dolls

[Bapsman1978]

Hi there, I'm new to the forum and sex dolls, I'm yet to purchase one and I'm interested in the robot dolls but I'm looking to see if anyone has experienced problems with them or not, due to mechanical components I'm concerned they might not last long and it seems the mechanical side of them only come with a 5 month warranty, so I'm interested to know if anyone has any experience with these?
