It took me a while to find the perfect strap on and this is IT!!!. The entire silicone unit is really soft and flexible- Including the enhancements. The strap is made of thick durable elastic that caters to individuals who are small in stature, up to extra large. It is super easy to put on. The attachments can swap over easily without having to take the harness off and they lock into place well. The hollow opening isn't huge but with a little lube around the entrance, it can be a pleasurable experience for the wearers living with ED too. There is also a space below the attachment as an alternative for him if he prefers skin contact with his partner. This isn't a cheap system but it is the only one you'll ever need. I give it 9 orgasms out of 10.
