Cabinets to Go Quality?

Seeking opinions or advice regarding Cabinets to Go cabinets. We've tried to find online reviews, but haven't found a lot. A few reviews note the following: Plastic corner pieces joining the panels in the corners and plastic anchors supporting the drawer slides, neither of which we expect to endure the test of time.

Are these plastic pieces standard in RTA cabinets and if not, is this a deal breaker?

They're currently doing a promotion for 45% off their Malibu White shaker style cabinet. We have to make a decision by tomorrow night as that's when their sale ends.

Here's a link to the link we're considering: https://cabinetstogo.com/products/malibu-white-collection

We'd welcome positive or negative feedback on the cabinets as well.

Thank you SO much for your help!
