I was disappointed in the product. Not much suction. Worked ok the first two time’s then not so much. I had tried the one with multiple size “cup” attachments with the suction gauge and that one broke after maybe 3 usages and it was quite expensive, (purchased from another site but it’s identical to the one you sell. I purchased the other one because I thought if would work better but it didn’t. I just feel these pumps in general are of poor quality. They’re a fun product if only they worked. Still glad for your site though.
