Vivitar does not try to be the top of the line. They give affordable quality.
I started using Vivitar lenses in the 1980s. Their products were decent then as a good substitute for the more expensive camera lenses. I recently purchased two action cameras, DVR 786 and DVR 757. Both have very good picture quality and less expensive than a GoPro. I contacted there support once to learn how to use the date stamp and received good instructions and friendly service. One has to realize that Vivitar has mostly specialized in reducing the cost of items. So if the top brand is rated a 10 on a scale of 1 to 10 I would expect Vivitar products to be an 8 on that same scale. I have never been disappointed with that expectation. Unless I win the lottery, I would never hesitate to buy a Vivitar product versus a top-dollar product.
