The price is very cheap and you get a lot of extra labels with this device, but it often jams during operation and the plastic thread does not attach easily. Sometimes it clicks, but it doesn't push the plastic thread through the clothing. One trick I've used for threading the thread (dangerous as it sounds) is that after you insert the needle into the fabric, hold two fingers around the needle while drawing on the tip of the gun Squeeze while holding the fabric on the tip of the gun before pulling the trigger. When you pull the trigger the plastic thread actually goes through, move your fingers and pull the needle out of the clothing.
