Du-Bro's Tru-Spin Prop Balancer is the most precise balancer on the market. Our NEW specially designed locking cone securely centers and locks props on to the balancing shaft for utmost accuracy. Each cone is carefully inspected on a calibrator to make sure it is running true. The balancing shaft is manufactured out of hardened material and then is centerless ground giving precision balance every time. The prop balancer's aluminum wheels turn virtually friction free for precision accuracy. The Du-Bro Tru-Spin Prop Balancer will balance model airplane props of all sizes and weights, boat props, spinners, car wheels, helicopter rotor heads, jet fans, fly wheels, etc. Each balancer comes complete with easy to follow assembly and prop balancing instructions. A truly precision instrument built for the modeler who expects the very best.

When it arrived, I took it down to the garage, set it up on my workbench and got started. The setup instructions were very easy to follow as well as the operation. Thanks to the review left by Mr. Helton, I knew that there were many videos available with the proper balancing techniques and found several in my first search that guided me perfectly. I initially wasn't expecting to be a huge difference as the props on my Syma X8G were still virtually new. Boy was I wrong. I took a video before balancing where I was basically just hovering facing the freeway and then another one doing the same thing after the balancing. The difference was shocking! Not to say that the first video was very poor, but it was like going from a 480p resolution to a 1080p kind of difference because the vibrations were minimized so much.
I have since used it to balance the props on all of my drones big and small with the same results. Not all have camera, so the micro drones for example, I do notice a more smooth flight overall with quicker turning response than before. I almost want to buy one more just so I can balance two at a time but I am resisting for now. I do not own any "high dollar" drones like a DJI and I have seen reviews about this not being compatible due to the rod needing to be able to pass completely through but as I do not foresee spending that kind of money on one drone, I do not see a problem.
The balancer with the Magnets, that celephane needs to be glued to is rather cheesy... I used, it over a few months and after long sessions of use, I got DECENT balance props that yeilded non jello video, but the Du-bro takes about 1/4 of the time, and works better.
With the cheap magnetic balancer, the cups, and shaft are out of balance from the start, making it nearly impossible to balance your props. Not to mention the shaft is bent, and if it isn't already it will be, as you have to stuff it into the grooves in the case/balancer arms, and if you aren't careful each and every time you pull out the balancing shaft, you can easily bend it. Just a very tiny bend is enough to make it so you cant balance these lightweight plastic props.
In case it isn't apparant by the picture, it has to metal wheels in each rest that mesh together and spin to prevent friction so that any weight will make it spin
So, yes, I took props that I had previously balanced on the magnetic balancer by a well known brand, and found them out of balance, and had to re-balance them.
Hope this helps! I definitly am glad I bought it! I wish I had chose this brand first!

Fyi, before balancing my prop the sound was uneven and during take off it going to one side like going to crash but manage to stop it.
I would recommended who ever had drone must have this balancing tool to make fly smoothly and steady.
Take your time assembling this. Make sure you are assembling it to fit the props you are going to test.
Their are some helpful videos on YouTube on prop balancing.
