Description

Cross-line laser levels offer the highest value of any type of laser: they're extremely versatile, easy to use and inexpensive. Johnson's self-leveling cross-line laser projects two crisp, clean laser lines simultaneously - one vertical and one horizontal. Its 360° graduated base makes angle layout a snap, and its locking mechanism protects the inner pendulum during transportation. Thanks to the laser's visual out of level indicator, you'll never need to worry about accuracy - if the laser can’t self-level, it will alert you by flashing the beam. This kit is all you'll need to get your laser leveling project started. The elevating tripod attaches quickly and easily to the laser for hands-free use, and the tinted laser glasses enhance beam visibility on the jobsite. And the hard-shell carrying case protects your equipment when not in use. Establish perfect horizontal and vertical planes with ease using the 40-0921 self-leveling cross-line laser level kit from Johnson Level. Handy for tackling a variety of building projects--such as installing kitchen cabinets or putting up a chair rail--this tool emits a cross-line beam and self-levels for optimal accuracy. It can be used indoors or outdoors and has an indoor range of 100 feet.40-0921 Self-Leveling Cross Line Laser Level Kit At a Glance: Projects horizontal and vertical lines simultaneously Self-levels to within plus or minus 6 degrees Interior range of up to 100 feet Backed by a three-year limited warrantyView Larger Use the 40-0921 to tackle a variety of projects--from installing tile to putting in cabinets Ideal for Installing Cabinets, Floors, Chair Rails, and More Made by Johnson Level, the 40-0921 self-leveling cross-line laser level kit is useful for a variety of building projects that require horizontal or vertical leveling--whether you're installing a chair rail, putting in kitchen cabinets, adding drop-ceilings, or framing a room.

🚀 Abunda's Overview

This is our summary and key points to consider based on customer reviews.

This Laser Level Kit is greatly valued for its excellent build quality, self-leveling features, ability to show both horizontal and vertical lines, and long battery life. However, the kit has noted drawbacks such as having an incredibly lightweight and short tripod, limited outdoor utility due to laser visibility, and high sensitivity to vibration.

Pros

  • 🎯 Great price-point
  • 💪 Good build quality of the level itself
  • 🧭 Displays both vertical and horizontal lines
  • 💡 One of the brightest non-professional laser levels available
  • 🔋 Good battery longevity using 3-AA batteries

Cons

  • 😰 Tripod is very light-weight and short
  • 🚧 Suitable for indoor use only due to laser visibility outdoors
  • 🎚️ Unit can only be used in flat, horizontal position
  • 👀 Laser can potentially harm eyes, it's not a Class I (eye-safe) device
  • 🏃‍♂️ Highly sensitive to vibration

Should I Buy It?

If you're looking for an affordable, indoor laser level kit with reasonable build quality and features, this could be a good purchase. However, if you need to use it outdoors or for professional-level work, its shortcomings including weak tripod and sensitivity to vibration might be a deal-breaker.

    • Better Than Most, but Some Drawbacks
Style: Cross Line Laser Level Kit
I purchased this unit only from Amazon. At the time, the unit was on sale and I saved an extra $20. This was a factor in my decision making. It was the cheapest laser level I could find that appeared to suit my needs, met a reasonable price point, and was available on short notice (Amazon Prime). Overall, I quite like this unit. It worked well for my needs. I used to own another, similar device that I paid >$300 for a number of years ago. This unit - while not as robust - is doing a decent job of replacing my old unit. What I like the most is it displays both horizontal and vertical lines, whereas my old unit only did horizontal. Bear in mind this is a light-duty, consumer-grade device. The laser level head itself seems very well constructed for this price point and target market. I have knocked the unit over a couple of times (with it on its tripod), and it has survived a 5' drop onto a wood floor. No perceptible damage or impact, which is good. If you are going to use this in a construction environment, it needs to be able to handle some scuffs here and there. So, from a build-quality to price-point view of the laser level itself, I'd give it 5-stars. The tripod OTOH is very flimsy and I plan to dig up my old pro-camera tripod that is decades old and use it instead. The tripod that comes with this unit should be considered only if you don't have a "real" tripod to use. It's a throw-away item IMHO. Thin, cheap aluminum. There are two big issues with the tripod from my perspective: a) it's too light weight, which means it's easy for it to be moved by accident, easily knocked over, and very susceptible to vibration; and b) it's too short. For example, I wanted to use this level to align a soffit in a room under construction, but was unable to utilize it for that particular task because there was no reasonable method of getting the level set to the necessary height (~8' off the floor). Caveat emptor if like me you are considering purchasing this for construction work. Though that said, I really like this laser level, so don't let that turn you off completely. Here's my comprehensive list of 'pros' and 'cons' to help you whether this product will suit your needs before you make a purchase: Pros: 1. Great price-point 2. Build quality of the level itself is good 3. Manufacturer claims self-leveling within 6° (all axes; x,y,z). I tested this and indeed it works, though I cannot confirm the maximum offset of 6°. 4. Displays a vertical and horizontal line simultaneously, so you get a cross (+) in the middle where the lines meet, at 0° vertical and horizontal axes. This is useful to ensure you have the device placed where you want it relative to your floor when using a tripod. 5. One of the brightest non-professional laser levels that I've used 6. Battery longevity is good (it requires 3-AA batteries; there is no wall plug) 7. Laser level may be detached from included tripod; has standard 1/4-20 tripod thread on the bottom of unit; bottom is flat and may rest on any suitable surface. 8. The (light) throw is good. I would estimate in a room with moderate to average lighting, you can easily get 16' of visible light. The included red tinted plastic glasses help increase that range slightly, or improve visibility in a brightly lit room. Cons: 1. Tripod is very light-weight, and constructed of (I believe) thin aluminum. I'd say the tripod is suitable for indoor use only. 2. Useful indoors only as the laser light will be too dim outside unless an overcast day or at night; however, this is typical for consumer-grade products such as this one. Exterior-rated pro units typically don't use visible laser light anyway. This is not really a 'con' so much as a warning if you are considering outdoor use (i.e. don't). 3. The tripod's maximum height is quite short. I didn't measure it, but would estimate the maximum height at about 1m. Perhaps a little taller, but no more than 4 feet tall. 4. The unit cannot be used in any position other than flat horizontal. This means it's less useful for certain circumstances, such as drawing a line level on a wall. It can be done, but you must move it away from the wall to do so. Not a huge 'con', but noteworthy. It is conceivable one could use velcro or another method to "stick" the unit onto a vertical surface temporarily, but I would not recommend planning on doing that. The laser level unit is relatively heavy for it size. 5. The placement of the unit often puts the user or other persons in line-of-sight of the red laser. This is not a Class I device, which means it is NOT eye safe. Be careful especially if you have small children or pets that will be in the vicinity of your use of the device. [note: I have a background in LIDAR systems; I know what I'm talking about here! This device CAN damage your eyes. There is a warning on the device (required by FDA).] 6. The unit is very sensitive to vibration. Walking on an unfinished OSB floor in the same room as the unit, every time I took a step the laser light wobbled (note: I weigh 175 lbs. FWIW). Once the vibrations stop, the unit stops wobbling after 4-6 seconds. 7. Carrying case is relatively flimsy, but suitable for indoor storage. It is made of light-duty plastic. ... show more

    • Laser hard to see outdoors
Style: Cross Line Laser Level Kit
Lets start with the things I like. I like the case to protect the laser. The tripod is a like because it was basically free. I like the lock out to isolate the laser when moving or storage. I like the fact that it has an owners manual in English. I like the fact that the owners manual shows how to re calibrate the laser . I like the overall design and ease of use of the unit. Now lets get to the things that I don't like. FIRE THE LASER ! The Batteries were not included and even the owners manual says that they are for this model. This sets off red flags right off the bat. The first thing I think is that I am getting a returned product. A lot of people will steal the batteries when the unit is returned. The tripod is cheap at best and junk compared to a good one. When you crank the handle to raise the shaft or lower it. It has a fill like plastic grinding on plastic . Lets get to my real complaint with the unit. The spec says visible up to 100 feet indoors depending on light. NO NO NO! That depends on if you have 10/10 vision an Apache helicopter night vision helmet and can fit those silly red glasses over all that. The first time I used it was 11.5 feet outdoors in the shade at 2.00 pm. I was wanting to set up drain grade for a stem wall with a drive way on top. Dream on MR Ricardo Montalban. THIS AN"T FANTASY ISLAND! With the red glasses on I could barley see the line. I put this thing back in the case and got out my transit and went back to work. I worked until dusk and got it back out maximum range 20 feet in low light. In side a house in daylight about the same. I plan on keeping it because I do a lot of work after the sun goes down and I can use it in the dark up to 25 feet. I also bought a red laser knowing it to be inferior as far as the human eye to green lasers. That's on me , also the fact that the government has restrictions on any laser more powerful than 5mw.
