I think mos has a product that goes over the entrance to make it smaller, tighter for a better fit.
Not sure if it works on bathmate, try the shop and the chat feature in the shop to speak to someone about that because if they fit it will solve this.
Thx DLD!
I forgot that i bought your Bathmate solution ring that you put on for better fit,found it in my case with the pumps i got from you.
Oh great just use that and you’ll never have this issue ever again. I did not know you had it. I was just trying to save you a little bit of money.
