Officially reporting in on my first day of using the divo cup. There were some problems with having to adjust the damn thing every hour or so, which requires a bathroom break. I can adjust it with just my index finger but the audible queef from my shaft would draw attention. Then at around 5hrs of use from 9 AM to 2 or 3 PM it just slipped off and nothing I could do would make it stay on again, Btw I was wearing a snipping of a masturbation sleeve to help it form a suction in case it started to slip. At that time I had to check myself in the mirror and as advertised my flacid was larger, head was impressive, and blood flow had increased better than ever.
The only thing I would advise guys here that are interested in this product is to slowly increase time wearing it by an hour every few days. Believe me, It’s enough pressue to wear even me out so take it easy. I have thought about making one minor improvement which would be installing a depression relief check valve so you could readjust without having to disrobe, but this would require a whole set of tools I do not possess (tap and die, drill, workbench).
My final judgement: Good pe investment. Not a requirement by any means, but worth the money if you’re willing to give it a go.
