Matthew H. ★★★★★ Oct 23, 2026

These dual suction cups hold my tablet mount firmly to my boat's dash even when I hit rough water. The 3.3" twist-lock bases give me peace of mind that nothing will come loose unexpectedly. A solid upgrade from my old single-cup setup.

I’ve had these dual cup mounts hold my tablet on bumpy forest service roads with zero slips. The powder-coated metal plate gives it a rugged feel, and the 1” ball makes angling the device really easy.

The twist-lock mechanism on both 3.3" cups makes mounting and removing this base a quick one-hand job, and the powder-coated metal plate between them feels seriously solid. I've had it on my dash for a week of rough roads and the ball hasn't budged an inch.
