Right, so there are pricier versions by the same company, but I had never tried something like this. It was an attractive price and a good introduction, so i went for it. I was NOT disappointed. Its deceptive when look8ng at it and applying it to your hand or finger to see what this 'suction' is like. It doesn't feel like much with your hands. In use though.....seriously, Less than two minutes. I haven't mastered edging with this one yet, but holy jeebus the multiples are amazing!!! If you're on the fence....go for it!!!
