Solid, classic; a little heavy actuation. This is a solid classic design that really gets the job done. If there were an opportunity for improvement, I would say the pressure on the handle is a little too heavy, or perhaps it is difficult to get the right leverage since the back of the handle is slippery and steeply inclined.
Reliable and Sturdy Tool. The T-50 delivers consistent, jam-free stapling. I have used electric staple guns, but I find the manual T-50 to be more consistent in punching staples into a variety of woods. The only draw back is that users need a certain amount of hand strength to squeeze the lever. Some may find this too difficult. But the electric guns still require the user to push down on the gun forcefully to ensure that the staples are driven deep enough. I also like the lack of a cord to drag around and get tangled.
