I have a brass hand pump that's the second in about 18 years. The first was ruined after maybe three years by water pumping. I have a 2.75" x 9" tube that I forget where I bought...it was bought around 2007. I also have a Monster Tube Jr. for pumping my cock and balls together. It was pricey (~$280) but works great...no risk of entrapment or discomfort in exiting while pumped, as it hinges open.
I only pump to get temporary size gains when the mood strikes. Over many years it has however increased my girth from 5-7/8" to 6-1/4". I'm reluctant to attempt a regimen as my wife already has some trouble accommodating me orally.
