Review on Bubble Furniture Trailers with Tripods & Machines by Joe Gilmartin

First of all I love these little guys, just what I need at a great price. I use them to align Model Railroad N-Trak and T-TRAK modules. These spirit levels are the perfect shape and size for the task, and are cheap enough to have a lot of. I can even install them on separate modules. I paid about $2 each, free shipping. Now for that caveat about "price". Ultimately, they're accurate enough, but you may have to click them. Sometimes the bubble seems to slow down a bit. I know it sounds weird. For example, if you tune very slowly and evenly, the bubble may not respond, it seems like it gets stuck at times. Sometimes a light pressure is required. But seriously, I am very happy with this product and the purchase. You just have to be smarter than the $2 mass-produced bubble level. Bottom up! stew
