  • This Johnson laser level looks very different than other laser levels you will see in the market. It is much less wide and kind of looks like a briefcase. There is a strong grip and that is why it is easy to work with this product while you are standing on a ladder.
  • It has a self-leveling option if you are working within the 6-degree angle. The graduated base is 360 degree which allows angle layout. The interior range is 100 feet. The products weigh only 5 pounds. It runs on batteries and you can constantly work on 12 hours with one set of batteries.
  • You can, of course, turn off the laser level after getting the marks done as doing so will make the batteries long lasting.
  • There are no complex buttons or anything, you just put on the required batteries and set up the laser level in a flat surface and it will give you accurate direction every time. The red signal is very powerful and this is why this laser level is perfect for both indoors and outdoors jobs.
  • It comes with water and dust durability. The cross signal is really helpful when you are trying to install frames. The signal line holds for a pretty reasonable amount of time for you to get the marks done, No need to hold the tool in one hand and do the job in other.


This laser level has lots of great qualities, and it is one of the most useful tools that you can get for your house. When you will use this tool you will realize that the brand made this tool with a lot of planning. The mistakes that are generally made with laser levels are all fixed in this one.

But it is the time that we do write some specific positive feature of this laser level which makes it one of the best tools ever:

  • The design of this laser level makes it one of the easiest laser levels if you want to carry it with you to another place.
  • While you are traveling with the product, you can lock the pendulum (This quality, in particular, looked very impressive as many other laser level tools do not have it).
  • The weight of the product is just perfect for everyone.
  • The red signal light is very strong, and it works effectively both in outdoors and indoors.
  • The products come with 3-year parts warranty.
  • The customer service will help you 24/7 in case you need any technical assistance.
  • It is easy to operate and you can change the angle very easily.
  • Has a very strong magnetic base.
  • Comes with its own tripod.

A free tripod in this price, if you do not think this is the best laser level then we cannot help you to find a better product.


Well, it is not possible to make a product that is absolutely flawless, so even this near perfect laser level has some flaws. We are not going to overlook it as we want you to get the best product. So let’s take a look at some of the disadvantages that this tool has:

  • The tripod only extends up to 5 feet at mos.
  • The spin on the base could be a little smoother.

But as you can see that both the cons are minor problems and you can easily overlook them. It is not hard for you to get a tripod that is little taller separately on the market.

How to use it best ?

Like any other laser level, you have to just put down the tool on a flat base directly to the place where you want to do the work. If you working inside a cabinet just hold the product and after you got the signal, make two marks. You can then put down the product and work as usual.

Who this product is best for ?

  • This Laser level can be used both for big construction works and household fixing. You can use it for anything, be it installing the roof, or putting down an extra shelf in the cabinet.
  • Use this laser level to hand expensive artwork or show pieces and your room will look more beautiful and no one can say that your hanging is crooked.
  • This is also great to do children’s project and many other things. The real value will be known only after having one and using this product.
