Just fine for what we want to do with this inflator. I inflate the tires of my car, my scooter and I tour all the bikes present home. Very interesting it is also able to program the desired inflation pressure and not let him do that, it stops automatically. Easy to use, just take the time to read the operating instructions. Only small problem that I have "too much hassle" a little is to inflate my bike tires which he did not mention that during the first use of the tip adapted to the valve, it must be created inner groove by screwing the force on the valve. After creating the furrow, more problems. I hope this note will be useful for future users. This information should be rising at Black & Decker elsewhere. A product that I recommend. It must be understood that this is an inflator and not a compressor, not to be confused.
