I've had both... Chinese clone, and original Atlas. The difference? The Atlas is a quality piece of workmanship that works today, and will work for years to come, and you can count on it. When you pay for an Atlas, you pay for top quality materials that will hold up to the intended task. You also pay for the American engineering research and development that designed the product. You also pay for the American worker who makes a decent wage to support his family and the health benefits he and his family receive from his employer. You also pay for the lifetime warranty the product carries, so if it does happen to have an issue, you aren't out the product you spent your hard earned money on. You also pay the profit an American corporation makes in exchange for conducting fair and reputable business, and providing American people a decent standard of living, and an acceptable workplace environment.
Wonder why the clone can be sold for 15% of the price of an Atlas? Because the Chinese don't have any of the above costs to cover. Quality Chinese clone workmanship does not exist. Clone materials are the cheapest, lowest grade available, bar none. Cloning a product by its very definition eliminates research and development costs. It's so much more cost effective for the Chinese to let the Americans (or anyone else for that matter) do this part. Any of you want to trade your pay, benefits and work environment for that of a Chinese factory worker? Go for it. Might not be all that bad... you could be on the same line as your 8 year old son. As for a lifetime warranty... I suppose they could exist on paper, but I'm not aware of any clones with lifetime warranties. When it breaks, it's broke. And remember, Chinese companies operate the way they do for one simple reason... Americans don't think American products are worth the cost, and we buy the Chinese knock-offs instead. Period. WE are the reason clones for anything sell in this country... because we BUY them.
Having said all of this, and probably getting the hackles up on every Atlas clone owner out there, let me say I stand guilty as charged by my own words. My first bipod was an Atlas clone bought on Amazon. Simply put, I didn't have $319 to spend right then, and I needed a bipod. I got the clone, and the very first time I tried to open the quick disconnect, I didn't get the release lever actuated all the way before pulling the locking lever open, and it literally smeared the metal of the release lever over so it had no holding function what so ever. That was how low-quality the metal was. The pan and tilt function was there, but it couldn't be locked reliably, and wobbled all the time. It was a bipod support, but it was NOT a stable shooting platform. But, it did work, a little. I decided from there on, I would not buy a clone again. I saved and purchased an authentic Atlas PSR bipod. It was the real deal, and worth every penny. Truly a rock-solid shooting support. I have since sold that Atlas PSR, and on the same basis, bought two Accu-Tac FC-G2 bipods, and I'm proud to support the companies behind both of these bipod products. To me, and for more reasons than just the products themselves, it has been worth waiting until I could afford them.
Hope my experience and opinion helps you decide on a bipod.
