What our customers are saying

Answers to all your questions

What are Alloi cases made of?

We use the best materials possible to optimize the performance of our case. There are four layers: (1) a seismic geometric inner plate for shock absorption, (2) a cushioned TPU liner to hold your phone in place, (3) a tough polycarbonate outer shell, and (4) our proprietary real metal composite coating. Plus, the buttons are coated!

How protective are your cases?

Our cases are designed to withstand the worst of everyday wear and tear, and it has the results to back it up. Don't believe us? We tried to break it, then ran over it with a car. It survived.

Does the metal interfere with phone signal, contactless pay, and wireless charging?  

Our design does not interfere with phone signal or contactless pay, and our case works with most wireless chargers.

Does metal make the case smell?

Nope! Copper is actually odorless. The smell we associate with pennies comes from copper's reaction with oils and other substances on your hands. Out technology is engineered to eliminate this reaction. Fun fact: pennies are only 2.5% copper! They stink.

Are all your cases antimicrobial?

Yes! All of our metal blends are >50% copper to ensure antimicrobial efficacy. 

Do your cases contain real gold and silver?

Unfortunately not, even though it looks like it — we want to keep our products affordable!
