Query: Doesn't work that well

This product doesn't seem to carbonate to the level of regular soda water from the store. I drink carbonated water all the time and what comes out of this tastes a little flat.The product also seems cheaply made. The first time I tried it, all the CO2 blew out the spout because the handle sits at a point where the valve is slightly open. I have to pull up on the handle when I insert the charger to get it to work.
