Hello!
I have used the Size Matters clitoris pump kit since I started testosterone. I chose that one (despite the off-putting name) because the cylinders are flared and the kit comes with three sizes of cylinder. This allowed me to progress through cylinders without having to buy all new gear and the flared base worked better for me pre surgery. However, it just broke on me this week lol! I got almost 6 years out of it so I guess it’s money well spent.
I am probably going to buy the LA Pump metal version as a replacement. I also plan to purchase the FTM specific advanced pumping cylinder since it has a flat base and I’d like to try the flat base with being post metiodioplasty now.
I have gotten all of the above items from tool shed toys. It looks like they still have the old version I had been using available on that site as well. It’s done great things for me, personally. My wife would say the same lol

Let me know if you have any other questions!
