It claims the cups are big enough to fit over a butt cheek, so I’d be worried that the cups might be way too large for your chest. Check the cup diameters and find out. What is the lowest vacuum pressure this thing can do? I see the measurement on the screen goes down to 3 cmhg (30 mmhg), but that doesn’t necessarily mean it can pump at such a low pressure. You’d have to ask the seller to find out what the minimum vacuum pressure is. Cupping machines can be very, very powerful. Sometimes chinese traditional cupping is done at such a high pressure that blood gets pulled
through the skin, which is almost unbelievable to me, but it’s possible. I doubt that this machine pumps that hard, but you never know. Breast milk pumps are generally designed to pump at a much safer level, and they’re cheaper. You obviously don’t have to use the nipple cups that come with them. You can usually swap the nipple cups out for full breast cups pretty easily. You might have to buy new tubing and connectors though, which can be annoying. There’s a system called “Bosom Beauty” that has pretty good components. I have issues with the way the owner markets the system, and the outlandish claims he makes. Regardless, I think he’s phenomenal at sourcing really good, affordable parts. Unfortunately, his profit margins are through the roof. I think he’s charging far, far more than he pays. At what point is a system so overpriced that it becomes a scam? That’s debatable, but he’s definitely riding the line, if not way past it. He also claims to have designed the parts, and I’m not convinced of that at all. The pumps in particular are almost definitely just rebranded nursing pumps from Alibaba or something. Bosom Beauty sells two types of pump, one that automatically shuts off after half an hour, and one that runs continuously until you turn it off yourself. I’ve used the one with automatic shut off and thought it was great, but it’s not really useful for the type of pumping I’m attempting to do nowadays. I’ve been trying (and failing, if I’m being honest) to pump overnight while sleeping. If your interested in pumping for many, many hours at a time, you’ll need a pump that runs continuously rather than automatically shutting off after short amount of time, like most pumps do.
This pump is very, very similar to the auto shut-off pump BB sells. I’d be very surprised if it isn’t coming out of the same factory:

You can probably find the exact same pump for a much, much cheaper price on aliexpress or temu, but I wasn’t able to find it. If you’re better at searching than I am, you can probably find it eventually.
This is very, very similar to the continuous pump BB sells. I strongly suspect it’s the exact same one, but of course BB has been implying they designed theirs themselves:

A set of Noogleberry cups and silicone rings (I don’t recommend their foam rings), costs at least $70 (about £54) not including shipping, depending on what sizes you need. That means that this entire system, including cups, rings, and pump, could cost you as little as $78 (about £101) not including shipping and any additional tubing you may or may not need. Seems worth a try to me.
