I love this buffer! I have wanted one for quite some time. I typically wash/wax my car at home often. Prior to this I had a buffer from Harbor Freight, but it was corded and not very reliable. It also vibrated really harsh - sometimes to the point where I'd get a headache after using. Not so with this cordless polisher from Niusken! This Niusken buffer is cordless and comes with 2 batteries which allows me the freedom to move all around my car without having to pull on extension cords, etc. Battery life is OK, but I probably would've chosen a 4000mAh option if it was available. Having two batteries allows you to keep one on the charger at all times. I used this product over the weekend to polish the exterior of my car. Holding it in your hand it feels very solid and well-constructed but not heavy. It's easy to maneuver and my hands didn't get tired while using it. Vibration was minimal. I was able to get to the entire surface area of my mid-size sedan, but I did need to use the 2nd battery. My wife's SUV also had a minor scratch, so I used some rubbing compound and "buffed" it out. I wish I had taken before + after photos as this thing made the scratch completely disappear. I was able to apply polishing compound and then gradually increase the spin rate of the buffer using the dial on the side. It's very easy to reach the dial with your thumb, even while the device is ON. The buffer itself is super smooth and easy to operate. The other thing I love about this kit is all the included accessories. There is a variety of bonnets, polishing pads, and even sanding discs included so you can get started immediately. No other equipment to buy other than the wax/polishes you want to use. Overall, this turned out to be a great purchase and one that will hopefully continue to last for many years to come!

This cordless car buffer and polishing kit is excellent! It comes with everything you need to get started multiple pads, and handy attachments. The cordless design makes it super easy to move around the car without getting tangled in cords. It has good power, multiple speed settings, and works smoothly for both polishing and buffing. The battery last a long time, and it’s recharge able ready to go is a huge plus. Great quality, easy to use, and perfect for keeping my car looking shiny and new. Definitely worth it!

The Niusken Cordless Buffer Polisher is a fantastic tool for detailing and polishing. The 21V lithium battery gives it plenty of power and long runtime, which makes it easy to work without being tied to a cord. The motor runs smoothly and has enough torque to handle waxing, buffing, or polishing cars and other surfaces. It’s lightweight and well-balanced, so it’s comfortable to hold for extended periods. The speed settings are easy to adjust, allowing for precise control depending on the job. Battery charging is quick, and the overall build quality feels solid and durable.

It overheats very quickly with even moderate use setting 3 or 4, the settings go up to 6, so this is underwhelming. For the price, it will get the job done, but every time you use it, you will wish you spent just a little bit more on a real one. It does come with two batteries. You will need to have one on the charger at all times, because they will not last through waxing even a medium sedan. Just a quick wax of a Camry went through 3 batteries...

I bought this for polishing granite after applying sealant. I also used it for areas that needed deep cleaning. It worked well as long as you use a high quality stone cleaner and sealer. Stay away from the cheap stuff . It comes with two batteries and it lasted a long time. I used this on an outdoor kitchen, island, granite backsplash, granite fire pit bordet and 16 feet of granite bench seats. After 10 years they all look like new. I didn’t even get through the power of 1/2 of a battery. I guess I will have to wax the car now. It is well worth the price. Buy the accessory pack as in includes microfiber polishers. The polisher includes foam applicators and wool like buffers.

This is a really nice well built polisher. It comes with everything you need to get started. It comes with charger, 2 batteries, carrying bag, and plenty of pads and attachments! It is a good quality polisher and does what you need it to do! It’s not loud, has plenty of power and comfortable to use for an extended period of time. I highly recommend!

This product is awesome. I had generalized scratches all around my car and the paint was looking rough. This was a great buffer and it got rid of all the imperfections. 10/10! The buffer isn’t too heavy which makes it easier to maneuver. Also, it came with an apron and many different attachments which was awesome. Highly recommend this product
