A ride-on sex machine is quite different than what the Ruby Glow Blush can offer, but they are significantly more expensive. Machines like the Cowgirl and the Motorbunny come with insertable attachments so that you can ride on them whilst also being penetrated, but they also come with grinding attachments. The Ruby Glow Blush can either be used as a grinder or a penetrative toy, but not both at the same time. It's also much smaller than regular saddle sex machines.
