Cheap materials and cheap feel, lezyne is no longer a premium name in my eyes. This is my second disappointment with one of their products this year. But most importantly, the gauge is not accurate. I bought this pump because it seems like every rim manufacturer is moving hookless and have strict PSI limits. The gauge on this pump reads about 8 psi LOW, so you'll be overinflating your tires. I measured it against another pump and my air compressor and a pressure gauge. What a waste.
