Works well, enough power to drive small staples. This gun is smaller than my old Stanley but lighter and easier to use. Standard T50 staples are available in lengths from 4mm to 14mm. U-bolts can be between 10-12mm and T-bolts can be between 10-14mm. Please note that the 5/8 inch poles which are US standard size are too long. 1/2" fits well. Replacement clamps and small size pins are readily available almost everywhere, including here at Revain. I have no idea where you'll find metric versions. It hasn't jammed (yet) and just keeps working. Solid five .
