I tried this product and did not like it. I asked for a refund but couldn't get it.
Many people on AHCAFR complain the same thing. That they ordered the product but did not get any refund when they did not like it. I read through the money-back policy, and I believe I would qualify. It is just uncomfortable and pretty tight on me.
I researched some forums and everyone says this about these types of extenders.
I did not try any other products, so I cannot say anything about those.
Pumps however, should not hurt because you use the water with them. I recommend people to just get a pump. Or even better, just do jelqing and that's it.
No need for any expensive tools. That's just my opinion about this.
Reason of review: Bad quality.
Monetary Loss: $300.
Preferred solution: Full refund.
SizeGenetics Cons: Hurts.
