My 2 cents on Shumuri cases.
I've purchased both the Shamuri Slim and Smoothie cases.
The slim fit well at first, but after about 6 weeks my phone started moving within the case. I was afraid it would eventually start scratching, so I removed the case. I put some clear masking tape on the inside to try and take up some of the slack, but the case didn't fit right along the front edges and annoyed me. I removed the case.
I did like how it covered the entire phone, but as I mentioned worried about it ruining my iPhone.
I thought I would try the Smoothie cases so ordered 3 cases in total...white, black and orange. All three were very big disappointments. The bottom, top volume button edges were extremely sharp. So sharp they could actually cut you if not careful. I ended up taking a nail file to smooth them out, but should have to do this to such an expensive case.
Case does have a nice feel, but extremely slippery in hand. I do worry about dropping the phone when removing from my pocket. The top and bottom are not covered as well like the Slim case. I expected the top to be covered as well, but could not see on their website.
Additionally, there were specs of dust under the paint on the white and black cases. I did contact Shumuri for a replacement, but have not seen the cases yet.
Their website does not accurately show the color of the orange case. The case is more neon in person and less soft orange as shown on their website. Its really not a nice looking orange and would not recommend.
I really wanted to return all 3 Smoothie cases, but when took it to the UPS store I found out it was over $25 to ship all three with a tracking number. This was shipping via USPS and at the cheapest rate. Shumuri recommends adding tracking number and I did not want the packages to get lost in the mail. At this point I figured it was just cheaper to keep the cases.
Even with the sales and promotions Shumuri offers, be sure to take shipping costs back to China if you do not like. Its NOT cheap. I did email Shumuri to try and replace the orange case for a white one, but they wanted me to ship it back at my expense for shipping. Guess that the price to pay for buying online and not in a store. In the end it would make more sense for me to buy a new white case as its almost the same cost as shipping my orange one back to China. I did not like the case enough to buy a fourth one.
Would I buy either a Slim or Smooth case again? Absolutely NO. I bought a $3 case off eBay that is equally if not better than both of these Shumuri cases. I've read other cases can be found on Amazon that are as nice, cheaper or even similar in style. I would go that route personally.
