Best All-Around Product EVER!

I LOVE LOVE LOVE THIS PRODUCT! I use it daily, not just when I go traveling; though it is also perfect for traveling. I love the pocket charger for when I need a quick charge throughout the day.I got the rose gold and the colour is rich and vibrant. It is sturdy and made with brushed (aluminum?) metal, not plastic and not made from cheap inner materials. It has a very good weight to it and I feel like I definitely got my money's-worth out of this purchase!The charging time for my watch from empty to full-power is only a little over two hours and the pocket charger gives me one full charge, when I use it. I use my red flashing micro usb to charge both the box separately or also when my watch is in the box. The power buttons on both the pocket charger and the box fade in and out while charging. The pocket charger can also be micro usb charged when traveling.The manufacturer and seller (same) were fantastic to deal with! My charging box came in just a few days - well before the expected date of arrival. When it got to me, it came in a hard board box sealed in bubble wrap and in a slightly larger shipping box. It was well protected during shipping from both the rough handling (during shipping) and also from the elements. Again, prior to E.D.A. I received a lovely e-mail after delivery (next day) asking if I was pleased with the product and packaging. They even inquired if I was able to use it right out of the box and if it was charged enough for use.The box did not come with the…

Disappointed w/ Sumato Watchbox

I wanted this to work desperately. Very disappointed. I tried everything to get it to work much to my regret... what a great concept it would have been. Would have loved to talk to Seller to get it to work. I hate leaving a review like this, but if it helps someone from making a mistake in purchasing, I must. No one wanted this to work more than me. Very let down.

It doesnt fit my 44 . Im extremely disappointed in this product. I spent $66+ for this product. I expect for it to work. The ONLY way I could get this thing to work is if I took the small Charger out and then it would only charge for 5 mins before it turned red.It the description would have said that I would not have spent the 66+ . The only reason it is getting the 2 stars is because it�s pretty that�s it

The MOST ELEGANT & High-tech Watchbox. Most Incredible Customer Service! Highly Recommended!

Sumato WatchBox is the BEST Apple Watch Case that Ive ever tried. It packs with a built-in power bank so you can charge your mobile phone anytime and anywhere. And you can also bring its removable charger keychain so you can charge your Apple Watch on the go. This is a MUST for those people who want to protect their Apple Watches and to be sure that you will not run of juice; plus the expensive look of the design. Sumato Watchbox is VERY ELEGANT, its made of Aluminum, truly very elegant and the price is superb considering its MFI Certified. But what Im so happy about is Sumatos Customer service. Its wayyyyy better than Apple CSR. They would listen and patiently answer your queries and provide timely and satisfactory support. Sumato WatchBox is HIGHLY RECOMMENDED!Disclaimer: This is NOT a sponsored item. I purchased it from my own pocket.
