Review on High-performance Aluminum Linear Bearing - QWORK SBR20UU by Isaac Simpson

Carrying four heavy boxes in a plastic bag that's not even as strong as a corrugated cardboard sandwich bag seems like a terrible idea. I ordered these four bearing blocks to replace the missing two that fell out of my pack of linear guides that came with two of the original four they started with. Please hire a packaging engineer to help you continuously replace missing parts from the grossly inadequate shipping packaging materials your products are shipped with. You don't make money if you keep having to send replacement parts to customers to cover the missing parts of your product, no matter how cool your product may be. This is just a little free advice from me, the average handyman who gets annoyed by situations like this. Just think of the carbon footprint of supplying replacement parts, or worse, returning a product only to have it replaced with another product (probably missing parts too in the same packaging). This doesn't even include lost productivity and personal time at each step of the return/replacement process. It's confusing and gives me an upset stomach which causes bloating... which also contributes to global warming.
