Top Customer Reviews
i LOVED the idea of this when i saw it at CES (well, i wasnt there, but saw sites talking about it). the one worry i had was how sturdy the battery pack would fit with the sleeve.
well, im happy to say it fits great! its very very sturdy. its very tight, and doesnt feel loose on the sleeve at all. when you put the battery pack on it all feels like one unit... the phone, sleeve and battery pack. im very surprised at how well it all fits together.
battery operation is very simple, and i noticed that when my battery got down low enough and i plugged up the battery pack it started charging automatically, i didnt even have to turn it on with the power button.
sleeve fits well and is very minimal which is what i wanted. im very careful with my electronics. i only dropped my droid 1 that ive had for two years twice, so this minimal sleeve worked out really well.
overall i think this is the absolute best idea for someone that doesnt need the battery on the phone all the time and someone that isnt clumsy with their devices.
If you are a heavy iphone user, and need more batter life, I highly recommend the uNuexera case for you. While a bit larger than the bare phone (have to fit in the battery after all!), it actually fits my hand better. I will also highly recommend the uNu dual charger, you can charge your battery easily.
I will be buying another uNuexera case for my wife as soon as she orders her iPhone 4S.
I would definitely recommend this product to my friends and family. Right now uNu Electronics Inc have the charging for Exera case. I can use this case with out charging my phone 3 day. How amazing!
