A little heavier than I'd prefer but effective. I like the refill window feature. Oh and be sure to get the correct staples, made 2 trips to the store to get it right.
This is my third T50, have two others at home. Needed one for work. Glad to see still made in USA, a major + in my book. Still a little tough to squeeze in tight areas, mainly upside down, but works well. Easy to load staples. I tried another brand, (craftsman pro) and the squeeze was a little better, but the overall impression wasn't any better. It's also made here.
Although I am sure this advised against, I used this product to hang my Christmas lights. It worked perfectly, without the staples being too tight on the Christmas wires.
