    • Good banjo.
Style: Adjustable,Unique
Really set the paper nice. If you use banjos or if you’re thinking about trying one, you should definitely pick this one up. It’s a great value for the money. Especially if you don’t do spackling professionally, but you ended up picking up a big job of 100 boards or more, you definitely want to consider this. Well-made, easy to clean. ... show more

    • Excellent product. A must have for drywall work
Style: Adjustable,Unique
Review Image by Michael S Michael S
What can I say. I loved this thing. It was a little messy, but less messy than not using it. I absolutely loved how easy it was to use. We remodeled our entire hose and finished our basement. This thing made light work of taping and mudding.

    • Love hate relationship
Style: Adjustable,Unique
Generally a decent taping unit. When full it’s pretty heavy. If you don’t fill it it it doesn’t tape far. The biggest gripe is cutting the tape at the end of a run. I would use the sharp corner of the tape knife to pierce the tape and pull. More times than I would like the tape would rip from the unit. Then you would have to open it up and expose the tape again. Got really annoying. Other than that it’s a solid tool for the money. ... show more

    • Great for installing tape!
Style: Adjustable,Unique
Love this! Used to install tape on barndominium that were building. I am a licensed builder who retired a few years ago and still love doing jobs for myself. Wish they had this back when i was in business, it works amazing except for cutting the tape when you get to the end of the run. But soooooo quick. ... show more

    • works great but very fragile
Style: Adjustable,Unique
I'm a contractor (not a drywall contractor) and bought this banjo for a large master suite addition. I only used it a couple of times and happened to drop it off a 5 gallon bucket - so less than 2 feet - and the roller attachment broke off. The machine is not really functional without it. Sent and email to the company with no response. The machine works well, especially the corner wheel for corners, but its very fragile. Buy the metal ones for the same money. ... show more

    • Cheap not worth the money
Style: Adjustable,Unique
Review Image by Byron Byron
So set aside that one of the pieces of the hinge was missing when I took it out of the box, I figured it would not interfere with its function and it did not.... Altho the door fell off almost every time I opened it.. I watched u tube videos on how to use and it looks easy enough... not so much... this thing is a pain in the butt to use...I used 2 kinds of paper tape one tore all the time and would not constantly feed without tearing and the other I could not get to tear... so maybe u could find the perfect tape and not have that issue but it is still very cheaply made and messy as crap to use I just decided to finish my job by hand way less mess and frustration ... show more

    • Ok
Style: Adjustable,Unique
Hinges broke early on. I took the front attachment off and added a 2.5 inch knife with a hose clamp. Now I can tear the tape with ease. Otherwise its not a bad banjo. Sometimes the tape roll will fall off when its almost gone.
