There is no on off button on ... *by A***Y on Reviewed in the United States on April 27, 2017* Hated it! There is no on off button on this charger, it took twice as long to charge than the mophi and it is thinner so I was worried about dropping the phone & having the screen crack. I returned the item to Amazon directly because the seller tried to offer me half of what I paid for it. If you do purchase this item make sure to purchase through Anazon prime so you can return for a full refund. ### ⭐⭐ Iphone 7Plus Battery Case FOSTO Ultra slim. Disappointed due to echo on the other person's side. *by M***N on Reviewed in the United States on September 25, 2017* August 4th I was so excited to receive my FOSTO iPhone 7 Plus battery case (ultra slim fit). This seemed like it was going to be my new dream case. My 7 Plus fit like a glove in it and the lenses and buttons were in perfect alignment. My phone held a charge it seemed like forever. I think after using my phone for two days the battery finally drained. Charging it up was a breeze. I believe it took 4 hours. I was traveling oversees in two days and set it aside to use for my trip. I had not made any phone calls yet, but it was working very well and I was super happy to have such a great looking and functional battery case that actually fit my iphone 7 Plus. When I got to my destination I called for my ride. The person on the other end had a hard time understanding me. She said there was an echo. I took the case off and inspected it, the seals seemed fine. I was 9 thousand miles away and unable to remedy my problem. Another customer review says this better than I can and I quote: "speaker holes are larger than this phone cover so when you slide your phone in, it echoes on the other people side, manufacturer did not allow for the same size width of the phone speaker in this model phone" I believe he is right. The quality assurance just wasn't there for this manufacturer. I wish they would have more pride in their work. Unfortunately, it's just a pay check for them. I am hoping I got a the phone case from a bad lot. Sometimes this happens. I hope the vendor will make good on his product and send me another FOSTO. I return the one I bought To the vendor: If you read this can you please respond. I would appreciate some kind of remedy when I return to the U.S. Thanks everyone for reading my review. ### ⭐⭐⭐⭐⭐ On time and right fit *by K***N on Reviewed in the United States on September 3, 2018* Happy with whole order --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/37748280-fosto-iphone-7-plus-8-plus-battery-case-ultra-slim](https://www.desertcart.id/products/37748280-fosto-iphone-7-plus-8-plus-battery-case-ultra-slim) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-08*
