The expression "Good isn't cheap, and cheap isn't good" comes to mind. Generally speaking, cheap gear is a roll of the dice. It might work, it might not. If it does work, the question becomes "how well and for how long?" and that depends largely on how you use it. Maybe the Caldwell unit is a hidden gem at an awesome price... maybe you're getting what you pay for. I don't have one, so I can't say.
When my dad started shooting more seriously, he bought a lot of value priced kit. Now he tells me what he wants, I buy a suitable piece of kit for him, and he reimburses me for it. My Dad is hard on kit just by his nature. If it can be broken during "normal" use, he WILL break it (shooting gear or not, this statement applies generally). He destroyed a number of optics, bipods, and other gear. He got tired of having his gear break/fail. I couldn't tell you the brand(s), offhand, of the (at least) four different bipods that he broke. I can tell you that he's running at Atlas CAL now.
