Complete waste of money. One vial/measure indicator is way too loose, the other won’t move without really hitting it. What you get for using cheap plastic for anything in measurement and especially not having some sort of appropriate locking mechanism. But then it is clear someone has absolutely no quality control. What really makes me laugh is they call the plastic bits “Slide & Lock(™) vial mechanism” one doesn’t slide, the other doesn’t lock!! Double fail and triple fail for BS marketing (you didn’t and would never be able to trademark “Slide & Lock” in any tool industry as their are hundreds of “slide & Lock” labeled devices from sliding tools to measuring devices. “The Ultimate Layout and Marking Tool” more like the ultimate waste of time and money. I am left with a chunk of extruded aluminum that I can’t trust to be precision, (are edges parallel along entire length, are the measurement marking precise or is there a fractional error that multiplies down entire length like one brand of measuring tape…” don’t know not willing to waste my time trying to find out. It’s going the damn recycling bin. Hopefully in this devices next life it will be something actually useful… like an aluminum bedpan. Will not be buying anything from this company again, and may have to swear off buying anything tool related from Amazon too. 2nd time in a month I have been taken for a ride and Amazon has only exacerbated the problems.

Great tool for hanging pictures or anything else that needs to be leveled Read more

Who knew a ruler with a leveler could bring so much joy to my life? First off, the quality is top-notch. This thing feels like it could survive a nuclear apocalypse and still draw a straight line afterward. The functionality? Chef’s kiss. Not only can I measure things with precision, but I can also ensure they’re level—which, let’s be honest, makes me feel like an engineering genius. Accuracy? Spot on. I checked it against another ruler (because I’m that person now), and it’s dead accurate. The leveler? Let’s just say my picture frames have never been straighter, and I may or may not have spent an afternoon leveling random objects around the house just for fun. Use? It’s versatile. Need to measure? Done. Need to level? Easy. Need to swat a fly mid-measurement? Surprisingly effective. And the value for money? You can’t put a price on this kind of utility. Seriously, I’d have paid double just for the satisfaction of knowing my lines and shelves are finally straight. If you don’t own this ruler, you’re living a chaotic, crooked life. Buy it now, thank me later. Read more

Very light and seemingly straight. The two sliding level pieces are made of plastic and don't slide very smoothly on the aluminum rail. The measurement markings on the rails, and notches in the plastic pieces (pencil locators), seem to be reasonably accurate. I use it for hanging pictures, art work, television mounting brackets, stuff that I don't want to drag out my heavier levels and tape. It makes one person measuring/marking quite easy. To get 5 stars it would need aluminum sliding components, which would increase the cost substantially. If you just need something around to quick hang something, it works just fine. Read more

I liked the Kapro 313 Multifunction Level Ruler so much I purchased the longer Kapro 314-48" Ruler for hanging larger pieces of art on the wall. The sliding markers make it easy to get the hangers perfectly spaced and leveled on the wall. There is no need to try and move a hanger to level a frame hanging on the wall. I would give this a 5 star rating but I dropped my 313 and broke one of the slides. I contacted customer service almost a year ago and I am still waiting for a replacement slide. From my perspective, this is a very handy tool but fragile. Too bad Kapro doesn't sell replacement slides. Read more

Appears to be a used product. Ruler has red marks on it and it’s missing one of the slide markers which makes it useless. When taken out of the box, the ruler wasn’t in the packaging and the one slide marker that was included was in the bottom of the box which was sealed upon delivery. Would not recommend. Wish I would have read the other reviews before purchasing! Read more

Best $20 (or so) I've ever spent. Just moved and for me one of the worst aspects is hanging decor. I need it to be leveled and exactly where I want it and because I'm not so great at it, some of my walls would like swiss cheese, and this would be after an hour or more of playing around. This thing I bought, took me five minutes to hand a 48 inch mirror that had two mounts on the back. I wanted to cry, I was so happy. I wish I would have bought this thing 20 years ago. Read more

The red sliders came out and did not stay in place. If the company could make the sliders stay in place it would be fantastic. I wish i could return it. Read more
