Conclusion
Having tried a few other premium options in this category, I would only recommend this item if you are curious to try one, as it is super affordable. However lack of clear instructions may make this more difficult for you. Creating an airtight seal is essential in using one of these, and for some reason, I have a very hard time with this after the first use. Lubrication is also essential, and I think some type of restriction rings should be included as I've seen with others, as it helps in maintaining the erection afterwards.
