Query: Cheap but have bought better for the same price

These calipers by Pitbull are not the best I've ever had. My biggest complaint is that the slider and channel are very rough and therefore are not very smooth when opening and closing them to take measurements...got to love that metal scraping on metal sound. Also, the sticker (with the ruler) was delaminating already when I opened them.I've bought some cheap $10 calipers before on Amazon and they were great, worked well for what I needed them for, smooth slider, and lasted for about 2 years before the display went haywire...so although these are cheap, I was disappointed when comparing them to others I've purchased for the same price.
