Ryobi 18V ONE+ – The Basics

This model is perfect for devoted enthusiasts who work with wood on a daily basis. As we already said, it’s not a perfect solution for professionals, but it’s more than enough for DIY-ers. The thing that makes this model worth checking out is its compactness. Due to its light weight, you can carry it around wherever you go without having to worry about fatigue or transport. The laser line up is also a pretty big advantage. In fact, even some of the more expensive models don’t feature a laser line up method. Therefore, you don’t have to worry about fine-tuning and alignments if you’re an absolute beginner because the laser method does most of the dirty work for you. Safety is okay, but far from impressive. Take a moment and check the user manual before you turn the machine on for the first time. Furthermore, check the safety precaution paragraphs in the manual because it can save your life.

The Ryobi 18-Volt Miter Saw Features

The design

As far as the design goes, the opinions are mixed. Some people say it could have been designed way better, while others love the minimalistic and compact structure. As far as we are concerned, the design has a couple of flaws, but it’s far from being underwhelming and unusable. For example, the handle grip isn’t cushioned meaning you’ll probably experience some vibrations, but it’s almost exclusively under full load. The vibrations are minimal when the machine isn’t under full load. The measuring components are okay. Even though it’s quite an affordable machine, the engineers responsible for the miter gauge and tilting mechanisms could have done a better job, there’s no question about it. However, as we already said, it’s not a professional piece of equipment; therefore, you cannot expect a miraculous performance under a vast array of conditions. In simpler words, the machine works fine to a certain point. Once you put a super-demanding project in front of it – you’ll end up disappointed.


Safety is one of the crucial elements of every power tool. If one feels that there is a lack of safety features, they shouldn’t buy it. This particular model has a few security systems, but it’s nothing out of the ordinary. The blade guard is transparent, which is an advantage. But, other than that, there aren’t any mentionable safety mechanisms.

Dust collecting

As with most affordable miter saws, the dust-collecting capabilities are okay, but you shouldn’t expect anything impressive. As a matter of fact, the dust bag that’s included with this model is of underwhelming capacity, to say the least.

Things we liked about it

The first thing most people like about the Ryobi ONE+ is its compactness and portability. Most artisans hate when they have to move their tools from one place to another due to the heaviness of the equipment. However, moving this particular machine is a piece of cake due to its 19 pounds of weight. The other feature we liked is the laser line up. If you’re a beginner, the laser method will save you a lot of time, nerves, and effort. Instead of having to align the blade manually, all you have to do is calibrate the laser and see where the point of interest is. Once you find it, the alignment won’t be an issue whatsoever.


Things we didn’t like

Dust-collecting is quite a problem. As we said, it does work well, but the capacity is simply unacceptable. You can rest assured that you’re going to discharge the included bag several times a day if you’re a frequent user of cordless miter saws. While it does have plenty of power, the machine is only useful for smaller cuts due to its size. On the other hand, it’s great for crown molding because it’s so easy to use.

What Users Say About The Ryobi 18-Volt

Professionals aren’t impressed by this unit, and it’s for a reason. However, the DIY-ers love its ease of use, compactness, and minimalistic design. The runtime is okay thanks to the 18V lithium ion battery, but it won’t make more than around 250 cuts with one charge. If you feel like it’s enough for your needs, don’t hesitate to check it out.

This model is made for a certain group of people. In other words, it’s made for the ones that have a strict budget. As far as we are concerned, it’s not a bad investment as long as you use the full potential of it. On the other hand, you can find a better unit for a couple of dollars more. In the end, it’s up to you to decide whether it’s worth investing in limited possibilities. Truth be told, it’s a decent piece of equipment, but far from ideal or perfect. The people responsible for the design could have done a better job, to say the least. However, the functionality is at a satisfactory level, and that’s what counts at the end of the day.
