I have been a bike mechanic for three years and have used many different types of repair stands. Since I live in an apartment, I cannot purchase a bolt-in-the-ground, type 100% secure stand; however, with the ultimate pro stand, I need not even look into any other type of stand. The wide base keeps things from tipping over. To make sure, I just tossed a few 10 lbs bags of beans on two of the legs, and I need not worry about anything moving. The clamp is 100% secure. The stand is compact and light enough to be hauled to any bike race or other cycling/tri event. I purchased mine when it was on sale and then I used a 20% off coupon from backcountry.com. You cannot beat that type of deal anywhere! Oh yes, and there was free UPS shipping as well.
