Larger Cup Holder + Phone Holder
Dan Grant—December 31, 2025
Excellent cup holder and design. I was able to twist it to expand the base to lock it in and offset the larger opening at the top to keep the cupholders next to it free for use. I especially like the phone holder that clips on. Keeps me safe - No more straddling things in my lap as I drive! Read more

Doesn’t fit iPhone 16 Pri Max with a case
Midlo Fam—January 12, 2026
Nice cup holder sturdy and fits securely. Adjustability functions as expected to hold a variety of cup sizes. Works well with my 36 oz yeti. Unfortunately I purchased this for the extra cup to hold my phone. I have an iPhone 16 pro max and it will not fit in the cup with a phone case on. Read more

Good price for a good product.
7thTicket—January 6, 2026
Returned. My husband didn't want it and I already have a different brand for my vehicle, but I think it would have worked well for him. If he wants his phone to constantly slide off the dash, so be it. Read more
