Review on Advanced Self Leveling Vertical Horizontal Rotating Rechargeable System by David Thomley

Well made, accurate and easy to use. As another reviewer pointed out, the instructions are terrible, lack information, and are poorly written. However, it's okay. Once you sort this out, you really have nothing left to work with. The charger works perfectly, but the labeling leaves a lot to be desired. The slots are for a 26650 battery, but they are actually 18650 batteries. The information embossed below says it will work with 18650s too. It also states that the input voltage is 100-240VAC, which is a bit tricky as power is actually supplied via a wired USB cable. By the way, the battery cover on the plane is also mislabeled. It shows + on both batteries facing up. That does not work. The level works much better when the left battery goes + and the right battery + goes down. All of these are petty claims of nonsense. Once it's running, the level works great. Evens out quickly. The ruler has five levels of brightness, so it can be used both outdoors and indoors. An extra set of batteries is included so you don't run out of power while you work. There are many other accessories. I give four stars because of the good function and the accessory package. This is a well put together product. I just want Chinese manufacturers to understand how poor documentation and stupid mistakes damage their image in the US market.
