The handle is long enough, so you won’t feel as though the machine lacks space when holding it. Moreover, this cordless polisher weighs about 4.9 pounds so that you can an easier time working for long periods.

Another thing that caught our attention when unboxing this machine is that it comes with an Allen key. That made the assembling process a lot easier as we did not have an Allen key on hand.

Unlike many other cordless polishers out there, this one does give an actual setting to set the RPM. So, don’t worry about figuring out how to set the RPM you want.

After going through many cordless machines, we’ve noticed that the speed of the machine decreased when we applied a little bit of pressure on them. Losing strength can be really inconvenient if you needed that extra strength to polish your car.

Things to Consider Before Buying

To get your money’s worth, you need to know a couple of things. Knowing those things will allow you to pick up an excellent and reliable cordless polisher.

And you won’t spend too much time memorizing those tips. So, it’s a win-win at the end of the day.

So, without any further due, here are five tips to help you choose a cordless polisher:

Battery Set

If you spend a lot of time at work, you will find yourself recharging your battery every so often. Sometimes this might not bother you, but if you’re in a rush, things get a little bit messy.

And depending on how much time it takes to recharge your battery, it gets worse. Thus, we recommend that you go after those cordless polisher machines that have two batteries.

If you do so, you will be glad you got two batteries.

Battery Gauge

It can be hard to keep track of your battery after working many hours in a row. And even if you managed to keep track of it, it gets annoying at some point.

So, a great way to get around that is to get a model that features a battery indicator. A battery gauge will allow you to have more control over the battery. And you will know when you need to recharge the battery. So, next time you want to get a cordless polisher, make sure it has a battery gauge.

Ergonomic Design

There are quite a lot of advantages you get from getting a cordless polisher with an ergonomic design. For example, such design boosts your productivity as you feel more comfortable using it.

It also improves the way you hold the machine. Your hands won’t feel as much tension, and this will reduce any risk of getting injured.

Because of that, every time we get a new cordless polisher, we make sure the design of the machine feels comfortable. Otherwise, that cordless polisher you thought about buying is not worth the money.

Long-Lasting Design

To get the most out of any cordless polisher, you must make sure that your cordless machine is made up of high-quality materials. Those that are made of cheap materials to reduce production costs are not worth your money or time.

In the long run, you will end up with a poorly-made product that won’t last many days until it meets its inevitable fate.

So, if you want to get your money’s worth, go after those machines that hold up well in the long run.

Adjustable Speed

Variable speed is an indisposable feature that any cordless polisher must-have.

Variable speed triggers allow the cordless machine to be locked at a certain speed. For example, if you want to set the machine to 1.000 RPMs or 2.500 RPMs, you will be able to do si with the variable speed trigger.

Because of that, we highly recommend getting a cordless polisher that allows you to adjust the RPMs as much as needed.
