Easy Seal - Never Use Lubricant Again- Pump not included for demonstration purposes only

I have used the smallest and medium easy seal so far, only in practice. They work well but I will the large one shortly since I think that will work best.

Immediate seal, works great but lubricant is still necessary

This product is quite comfortable and it's nice not to have to use the lubricant --it made for a more enjoyable experience. You need to be careful when stretching it over the tube not to accidentally nick it with a fingernail or pull unevenly. It can tear pretty easily, but if you are aware of this, you can easily avoid the problem.

it works fine without a lubricant but pulls off with difficulty.

This product works as advertised. It saves time and is very comfortable.

This is a fabulous add on to any of the Erecaid pumps. I still find that some lube is necessary but it creates a great seal and virtually eliminates the very painful problem of testicles being sucked into the tube.

I had to use lubricant but the results are the best yet for an erection. Highly recommend with use of a constriction ring because there is no vacuum loss when ring is slid onto the erect penis to maintain an erection.

Greatest device invented. Period

I just started using it and it works great, as advertised. Only a little lube is needed, and it's very comfortable to use. The best benefit is it really prevents the scrotum from being sucked into the tube - I've not seen anything else that can do that. Performance wise, it's 5 stars. I deduct 1 star for the high cost (it's basically a large heavy duty condom with a hole in the tip) and durability is unknown. If it lasts at least 3-6 months, I'd bump it up to 5 stars overall.
