Watch a quick tutorial video once and then just practice and learn your own way after that. I realized I was doing a different technique than any on the videos before actually fixing myself, but find that I use the one I taught myself the most. You will get the hang of it relatively quickly. The magnets are good, but as one other stated the spinning can get sluggish over time. Soap and water will fix this and I also threw some rubbing alcohol in it as well and it was good as new. In case you think, " I can grease it up" or " use WD40" to make it spin better and faster...don't bother it will spin slower and you will just end up washing it off. I have dropped mine plenty of times without damage as I am sure you will to as there is an initial learning curve when spinning it. To hard it flies off, to soft it doesn't go far enough. Delivery takes about a week and half to two weeks (business days), I assume depending on where you live. All I can think of... only one I don't own are the wooden ones. Maybe one day I can! Very curious to try them out. Oh someone mentioned the magnets possibly getting weaker. Magnets do get weaker, but i am pretty sure the strength can increase. I will run some experiments, but wouldn't recommend in the meantime unless the people at Fingears give you the okay. As of now, mine are still magnetized just fine with no loss. K, Later!!
