I have seen a lot of pumps, but not that one. I always recommend the LeLuv brand, but for the one with a hand pump with a pressure gauge and a cylinder with a quick disconnect so you can buy different diameter cylinders depending on your girth.
That smart pump just has one cylinder size and they don’t specify the diameter. I hope it is 2" diameter as that size is generally the best for most guys. The 9" length is good.
This is the pump I always recommend: https://www.ama … /dp/B00LAF4UH8/
