Document: works great better then I thought would recommend it for anyone doing woodburning gets up to temprature fast and burns the wood with out any problem
used 3 or 4 times so far no problems. made some Christmas decorations had fun with it. not as easy as it looks.
tools for the pleasure of wood burning. Comes in a cute little case, Enoughtools to keep you happy with shading and evan a small tip or embossing  on leather.A real bargin with the price and I love mine.Great gift for the crafer in your life, or better yet, Get one for yourself!
this was a gift for my sister-in-law and she loves it. Has made a lot of wonderful wood designs and having fun being creative with it.
socket for tips bent under light pressure, threads stripped out third time I changed tips. Piece of junk. Would not buy another.
it looks good and organized, but it is for light use only, it does not have too much power, I  like it.
i love the new tips this tool has to offer..the only thing i don't like about this tool is that it doesn't have an on and off switch like all my other burners...but it works fine and well worth the money spent on it..
i got this mostly to do pattern transfers onto wood for logos, I tried a bit of wood burning, and did some stippling on a plastic knife handle. the reason i gave this 3 stars instead of 5 is that the grip portion up near the tip gets too hot, slightly painful to the point where i cannot use it for extended periods of time.
great little setup for hobbyists
don't pay more for the other kits that have wood and colored pencils- or less for the skimpy kits in the blister pack. This is the best kit with the most tips per price and an excellent sturdy case (on amazon currently, at least)
