Review on Bubble Furniture Trailers with Tripods & Machines by Brandon Mercado

Excellent value for the price. I bought a set of these and a set of small level cubes. Together they were perfect for leveling my rifle, leveling the scope and then checking that both were calibrated together. Because you get multiple levels, if one or two aren't perfect, fuck it! Just pick a few that are accurate and then use them. Very happy with this purchase.
