I have used one for the last few years and if you take time to seal all the joints it will be seviceable, although I wished I ahd bought a bigger one than the one I have and it is the largest that hf had at the time. I am working on my last big project so it will just have to do the job.., if you can get
them to throw in some extra plastic glass protectors, they are hard to come by, also the light setup in them sucks, I ended up putting 2 halogen in the top so that i could see what i was doing, use in it now are the glass beads, no more black beauty or silica sand, once you get one set up you will use it for most everything I Know I sure do....
