Most people just wax and plexi-scrape their snowboard or skis and are done with it. To get the best glide out of your stick, you need to remove as much wax as possible from the surface of your base. Roto-brushing really goes that extra step beyond hand brushing to get as much wax off your base as possible. This kit is easy to use and works as expected. You can nylon or horsehair brush at normal drill speeds, but the brass brush should not exceed around 800rpm to avoid damaging the ski/snowboard base.I didn’t have a lot of luck with the cork, a flat hand cork still works better, could be my lack of experience though. Brushes are great for sure, waxing is quicker and better with this and an m12 drillNo more manual brushing, this tool is amazing!I've never used brand rotobrushes so I have no comparison basis, but these definitely do the job.It took me a couple of pairs of ski, but now I have a good routine and I can change the rotobrushes with two flicks of the wrist.rEDUCES WAXING TIME. HAND BRUSHES ARE COMPARABLE IN PERFORMANCE BUT TAKE A LOT LONGER. USE AND BRUSHES FOR TRAVEL AND ROTO BRUSH AT HOME. CONSTANT WAXING MAKES A BIG DIFFERENCE ON SKI PERFORMANCEJust used it on 3 pairs of skis that I had hand scraped and brushed off summer wax. I used the brushing and buffing attachments. The brush removed a considerable amount of residual wax and the yellow attachment buffed the remainder into the base so that the stone grind structure was exposed. Huge improvement over doing it by hand. Also much faster.It saves the most time consuming time of ski tuning by doing a couple of quick passes with the brushes. I always coveted my friend's Swix RotoBrush when I tuned my skis over at his house, but couldn't bring myself to spend the $200+ those cost. This one has 3 brushes included for about half the price and works 90% as well. I do think the swix version threw the wax off better, these bristles are probably a little shorter or something. This one takes an extra pass or two but it beats the heck out of hand brushing. I'll wax my skis more now that I don't have to take the extra time brushing.I have to do 3 snowboards in 1 set of skis every time and this product saves me at least an hour and a half of brushing.Vereinfacht die Arbeit mit sehr gutem ErgebnisBei > 2000 km Skifahren/Saison mache ich meinen Service inzwischen selbst.Die Bürsten sind eine große HilfeThey are in goood quality and do a great job, except the Nylon one is little bit tie to put on and take off from the handle rod.I can wax my board in no time flatpour l'entretient de mes ski alpins et de fondSo easy to use highly recommended
