Overall this toy is too powerful for us. It is quite small in size, but it can really suck. It will give your skin a hickey that lasts a while in less than a minute. I consider it a big flaw that this toy does not have a pressure regulator among its settings. It's full power all the time. Among the alternating suck patterns, there is no mild or medium option. The patterns themselves are great, like morse code: long-long-short-long suck. And there are 7 different patterns.

The silicone tube between the two cups is 11.75" long, which with some bend in the tubing to orient the cups to the nipples, means the max distance between the cups is something like 10". In other words, they will not reach both my nipples. Luckily they can reach my partner's. They suck hers impressively. Maybe we will get used to the power, but at this point, we are being cautious and taking lots of intermittent breaks.

To get proper suction, both cups need to find traction since they share the same tube. But this is not hard, and you don't need lube or hardly any spit; it sucks hard enough it will pull your skin into the cup effortlessly.

This is a compactly sized motor, but it produces a lot of noise to get that powerful suction. The console is simple and lights up when it is on. It is USB chargeable and holds plenty of charge for our purposes.

Overall this toy would be perfect if it had a pressure regulator, and I'm going to attempt to install one into the line so that we can enjoy this for longer sessions of pumping.
