Review on 🛠️ DOWELL Hanging Bubble Line Level Mini Spirit Line Level 6-Pack: Essential Tool for Building Trades, Bricklaying, Tiling, Engineering, Surveying, Metalworking, and Measuring - HY030637 by Jared Gopalan

- This 6 tier set is very lightweight and versatile. They weigh only 6 grams and are 7.6 cm long. - Cord hooks are curved so they won't fall off when you shake the guide wire. - V-groove on the bottom allows the spirit level to sit on top of the tubes and on the sides. The pocket clip on the side is pretty flimsy and only attaches to a shirt pocket. Anything thicker (like jeans) will be too thick and will bend the clip. Compared to my trusty spirit level, these little spirit levels gave the same reading. Essentially this means that they are correct and of a good level. The review above is about Dowell's mini-mind, the Linear Planes.
