Greetings Everyone!
Though this is and can be embarrassing for us, it's a fact of our lives now and sharing valuable learned information can be quite a value. I like researching to see what people are saying prior to making purchases and this was a popular model....so I ordered one. I can't see any drawbacks whatsoever and it is very well made. They have a long warrantee also. I hope it's ok to add a link to my message.

The restriction rings that come with this pump I found to be very painful to use so I tried these blue rings below. It's an extra cost but well work it. Not really painful due to the much softer material and they are wider.

Since a person doesn't know what size will work, I ordered all three sizes to be safe.
I know a person can get set up with a pump with these rings on this site with a pump other than what I bought and save money. I'm just letting everyone know what I've used and have been impressed with.
Good luck to all....we are all in this challenging situation. There is so much more I could say on this subject...
