Previously, the difference from a similar product (somewhat expensive) that I had purchased was whether it can vary the width to be added → This product can not be adjusted. However, as long as you do not put very thin cans and bottles, there is no problem even if you can not adjust especially for general items. It is good to be cheap and adjustable, but considering that I always have to wonder if the screws are loose or not (because it is a motorcycle with many vibrations) I thought this was enough. Especially because it is this price, I do not have any complaints. I bought a good one.
