I bought a knock-off noogleberry https://m.media-amazon.com/images/I/51OjtUtawNL.jpg because I wasn't sure if pumping was for me or not, but the cups vacuum doesn't really pull my skin (initially) as much as it digs the cup's edges into my skin, which stay for almost an hour! For some these knock-off cups might work, but they are not what I expected at all... I also think my nipples are a bit far apart, while the cup is on the edge of my armpits (should I put it directly above my nipple or not?)

The airlock is also kind of shitty, and I sometimes 4 pumps feel as strong as 3 pumps. I saw that NB has a pressure gauge handle and much nicer airlocks, but it's very hard to see on pictures what actual noogleberry cup edges look like.

Can anyone give me a close-up picture of the cup and/or silicone ring before I spend so much money on a noogleberry system?

I believe  these are the same ones I got from amazon used coconut oil as a lubricant all over my boobs. I got a good vacuum but the domes are very thin plastic and did not last long and cracked --thus no suction.  Went with some of the butt domes which are a heavier plastic. Used a lawnmower gas shutt off valve which works -, get them at any lawn and garden supply shop.
