GORILLA GRIP Patent Pending Adjustable Car Cup Holder Expander, Black

Why it's worth it

The GORILLA GRIP uses adjustable arms rather than a fixed ring, gripping bottles from 2.8 to 5 inches across and up to 48 ounces. The open sides leave clearance for handles, and EVA foam pads hold the bottle without marking the finish.

The open-sided arms are what a handled Stanley actually needs. Closed-ring expanders fit the base of a 40-ounce Quencher but leave the handle nowhere to go. GORILLA GRIP's arms open at the sides, so the handle passes through instead of fighting the rim. If your bottle has a handle, this is the design difference that matters most.

It reaches diameters nothing else here approaches. The arms adjust from 2.8 all the way to 5 inches and take bottles up to 12 inches tall. That covers an 18-ounce tumbler in the morning and a 48-ounce jug at the gym without swapping products. Everything else in this guide caps out near 3.8 inches.

What we like

• +The open-sided arms are what a handled Stanley actually needs
