Overall this is a good compressor. Build quality is good, it's not rugged like some other compressors I've owned with rubber treads on both sides. With no rubber and given the length of the compressor air cable, when inflating large disks, the compressor must be off the ground (when the valve stem is at the top of the wheel (12 o'clock position). So in this case it vibrates and scrapes. You can do that Simply turn the wheel forward or backward to avoid this. This does not affect performance. This works well enough for semi-regular use. Comes with extra fuses and standard adapters. The lamp is brighter than most compressors. The LCD display, which mimics an analog gauge is pretty cool, as is the auto shut-off for a compressor in this price range.
