Very sturdy and well made 3-d print. The print was very clean and had sharp details

This is the second time I have ordered a custom item and just like the first time, it was perfect. It arrived just as described and on time. I would highly recommend this seller.

had to shave down the edges a tiny bit for it to fit but honestly believe that was because my umbrella base was a bit warped. Otherwise... great product I couldn't find anywhere else.

The item doesn’t quite fit snuggly in my color cupholder, but it’s OK. It will do.

Thanks for your review! Can you share details of the item you're inserting in the cup holder adapter? There are a lot of different variations of items that could or couldn't fit in the adapter.

Great fit on the treadmill. I would like it to be a little deeper but it fits very well and shipping was fast.
