The Measure Up Pump does exactly what it is expected to do. Using one of the interchangeable ends based on the size of your cock, the pump fits wells will give you plenty of suction. The pump is a basic bulb with a small steel release valve to relieve the vacuum. You can pump it till it won't pop back for another squeeze. I had no problem with it losing vacuum on any of the occasions I tried it. I would recommend adding a little lube to your cock prior to use, as a dry hard cock being pulled against the plastic as it grows is not something you will enjoy. I will say that the pump gave immediate results in getting my cock nice and hard but my wife can do that with her hands and mouth too, (I prefer the hands and mouth). This and a good cock ring will extend the fun if that's a problem.

The clear plastic tube has both length, and girth, measurements molded into the material so you can see how long and how big it gets. These are a little hard to read as they are clear plastic. A little color on the text and lines would help. As with any pump, there is no lasting affects to the size of your cock. Also there are warning not to use it too long or too often. Some web search results say that repeated use can lead to desensitizing your organ. Not a side affect that I would want. I've seen quite a few pictures of people who say they pump often and some have done severe damage to their organ.

Does it do what it was say it can to do - Yes. Is it something I will use often - No. Does it add to my sexual enjoyment - No not really. Anyhow my wife likes my size and if she needs something larger we've always got a nice Ty Fox Dildo that can fill her up when she craves a real big one.

OK - The pump still doesn't do anything more for me. Could help you if you had a problem but not "growth."
