Got this for a Valentine's party (ordered heliums pre-inflated) for latex balloons only. Worked ok, as long as you seat the balloon neck correctly on the ridged nozzle. Does the job at a modest speed, the thin pumping stick (not big enough to be called a handle) is a bit insubstantial but no sign of it breaking, just not easy to get a grip on. Having read some reviews of these things I bought two in case one broke half way through but it lasted fine and no signs of being that fragile. A more substantial body design than many I have seen; I only did 12 balloons but I am sure it will get more use. Can't rate durability over long time, other than it did the job I needed it for. For the price who can argue
