REAL REVIEWS FROM REAL PEOPLE

Dwaine S.

I damaged my case by dropping phone between car seat and door causing a gnarly gash on the bottom of the case - warranty covered it and I had a brand new case days later. Talk about a company who stands behind their product and delivers on customer satisfaction. I will be a Bullstrap customer for life.

Jacob W.

Submitted a claim for their lifetime warranty and they had a new case in the mail in about 24 hours. The cases are great quality but it’s helpful to know you have the backing of a legitimate warranty.

Keith M.

I couldn’t believe it! I inquired about their “lifetime” warranty on a case that I have loved for two years. They held up their end of the commitment, and replaced it due to a couple corners that had chipped off. Thank you. Can’t wait to get another Bullstrap case for my next phone.

FAQs

Is this product really covered by a Lifetime Warranty?

Yes, it’s real. And it’s awesome. If you want to read some legal nonsense, you can learn more about our Lifetime Warranty policy with the link at the bottom of the page. But suffice it to say, we’ve got you covered.

How many cards fit in the portfolio case?

Our Portfolio iPhone cases allow for 1-2 cards per slot, adding more than the recommended amount will stretch the stitching and potentially damage the case.

Are your cases compatible with wireless charging?

All of our iPhone cases are compatible with QI (standard) wireless chargers. Including our Portfolio iPhone cases (even if they have IDs/cards inside them).

How much protection do these cases offer for dropped phones?

Our production and research team has conducted a series of drop tests across the different sizes of phone cases that we offer. After conducting these tests, we’ve concluded that anything within a six foot drop is where we know the phone/case remains safe. We’ve obviously had tests where both the phone and case consistently survive harsher throws and drops, but within six feet is an extremely safe range.

Are Bullstrap products waterproof?

While our high-quality genuine leather Bullstrap products are splash/water resistant, we do not recommend submerging it in water as it will cause the leather to darken considerably and become more firm. We recommend using our Leather Care Wipes for keeping your leather accessories in it's best shape!

"A superior phone case. Superb craftsmanship. The case feels very durable and has already developed its own patina after just a few weeks of use. You get what you pay for. Cheap is cheap. This is not that." - Brian B.
