Very nice case and all the gears are moving, so I'm happy!

10 Jun 2020

I am a teacher and my students love this case! Very durable and exactly like the picture. I sometimes give it to them to relax before the test, so it’s multipurpose too.

10 Jun 2020

EVERYONE AND I MEAN E V E R Y O N E wanted to spin this thing. This is how yiu become popular. Also, I dropped my phone like twice in this and it was protective as heck. You don’t even know.

10 Jun 2020

Very nice case and all the gears are moving, so I’m happy!

10 Jun 2020

Awesome keeps the phone very clean inside from debris I’ve taken the cover off a few times, and the phone is very clean and stays put,it feels very nice to hold and it’s so much fun to spin the gears, I am very happy with this purchase. Thank you!

10 Jun 2020

When I bought this I was skeptical about the amount of protection and possible signal blocking because of the metal. However, it turned out to be great and I am very happy with the unique look and protection it provides.

10 Jun 2020

This phone case is AMAZING! I honestly didn’t want a case because my iPhone is pretty and I appreciate the design. THIS CASE looks so nice!. I love this case and won’t be buying any other kind because it’s so much fun and makes my phone look very unique.

10 Jun 2020

Love this case! So far, seems to protect well. I’ve dropped it a few times and no chips or scratches on the case and phone screen is in tact (I have a protective glass screen cover). It’s slightly raised from the screens surface so the screen won’t touch the table if you lay it face down. Easy to hold and fits well in my back pocket.

10 Jun 2020

For the money especially, this is a great case.

10 Jun 2020

Use this for my iPhone 8 and it’s very protective. Wireless charging still works, despite it being a pretty thick case.

10 Jun 2020

I don’t usually write reviews but I feel compelled to do so on this item. I work construction and today I was 50-60 feet in the air I’m a boom lift. I took my phone out of my pocket to see what time it was and I dropped my phone and watched it fall to the concrete ground below me. 50-60 deer BELOW me!!!!!! I was certain that when I got to the ground I would find my phone in pieces and at best just not working any more!!!! To my surprise it was totally fine. Working just like new as the phone is only a month old. I have a small sent in the bottom corner of the case where it hit the ground first but other than that JUST FINE!!!! What a great item. I will order again.

10 Jun 2020

The case is slim, which is nice since I hate bulky cases. I can easily fit this halfway into my pockets (only half way because that’s all the pocket women-marketed jeans have ugh). It also fits easily into my phone-holder armband that I use when I work out which is SUPER nice.

10 Jun 2020

PROS– + Durability is without question; this thing can handle everyday drops no problem. + Cutouts don’t obscure ports, speakers, and/or camera + Tight fit, as is the case with many 2-piece designs. CONS: – It’s a bit slippery

10 Jun 2020

Super cute case. My daughter loves steampunk and this was a fun case for her to get.

10 Jun 2020

Got it as a curiosity. Looks good however I work in a bit of a rough and tumble job and after seeing and feeling it I do not recommend this for anything more than light duty usage.

10 Jun 2020

This case was purchased for my daughters birthday and she absolutely loved it…Her birthday was back in January and she still has it and it’s still in perfect condition

10 Jun 2020

I just returned from a trip to Disneyland. My kids and I went on a ride in California Adventure called Goofy’s Sky School. Well, due to a lapse on good judgement, I did not secure my phone when I got on the ride. I was wearing a hoodie with a front pocket-pouch. My iPhone was in that pouch. Well, I lifted my hands up once the ride started and at some point during the ride (I don’t know when) my iphone flew out! I didn’t realize this until I was walking away from the ride and couldn’t find my phone. I freaked out, rushed back to the ride attendant and asked if she could check each car. No phone. She said to come back at closing time and she would check the area underneath the ride. I feared the worst. I went back later when the ride was shut down, my daughter pinged my phone and they found in under the ride! The miraculous part is that the phone itself was NOT damaged at all! I believe it was all because of this and the glass screen protector I had on my phone. The only thing that cracked was the glass screen protector but that’s because it was doing its job!

t’s just like I hoped it would be

10 Jun 2020

I just love this phone case it’s my favorite if you are into steampunk and spinners and cute stuff this is perfect I’ve had this product for a month and have had no problems still looks new and it’s super fun to play with when you’re bored

10 Jun 2020

Looks good just wish it was more durable my son got to it and ripped apart, so it’s not completely baby-proof. Must’ve taste nice though.

10 Jun 2020

The materials feel very good in your hand. The case holds the phone snug. I’m quite pleased with the aesthetics it looks good protects the phone and it doesn’t make it bulky like some case’s.

10 Jun 2020

Exactly as advertised, super cute, love it!

10 Jun 2020

I liked that it fit just right and that it is easy to put on my phone. All the openings in the case fit the phone exactly. I also very much like the design. Not sure about durability, but it looks and feels like very good quality.

10 Jun 2020

This product is nice overall, the case is more of a rubber material so it’s easy to slip on and off. Really the only issues I could see with it is that if you are looking for a thinner phone case, I wouldn’t recommend this one since it is larger in thickness

10 Jun 2020

Im in bed sick today and this arrived and made feel a little better so ty! It feels a bit strange to hold but not bad. I love to just play with gears while resting.
