How does it perform?
The ClearBoost case is a two-piece (top and bottom) case that snaps together, encasing the iPhone snugly within. There's never a worry about the iPhone sliding out of the case, as can happen with slot-loading cases, as the two halves snap tightly together. In fact, you need a small screwdriver or a quarter to pop the two halves apart.
However, the hard plastic case material, while tough, is slippery. I was immediately struck by how smooth the case was; there was no sense of tackiness or grippiness to the material. I used the ClearBoost for a couple of days, and had it accidentally slip out of my hands more than once. Also, there is no belt clip, so the iPhone will have to live in your pocket or purse.
The main selling point of the ClearBoost case is improved cell phone reception. That's the "boost" in ClearBoost. Inside the bottom case is an unpowered antenna that sits firmly against the back of the iPhone outer shell when closed. I'm not enough of an electrical engineer to know how the induction works to transfer the signal from the ClearBoost's antenna to the iPhone, but Griffin says there is a marked improvement.
Part of the review package is a white paper telling reviewers how to access the iPhone's Field Test Mode to measure the cell tower signal strength. I tapped in the code (*3001#12345#*) and went to Cell Information.
I live a bowl-like depression in the foothills of the Catalina Mountains, in the northern part of Tucson, AZ. ATT's cell phone coverage is usable, but just barely.Read more ›
On the negative side it is an ugly case. It looks like the army designed it to be rugged. It is thick enough to make accessing the iPhone controls or swiping your finger more difficult. The nub antenna, however, has not been an inconvenience. It still fits in my pocket well.
The case comes with a plastic screen protector that is the worst part of the product. If the case is ugly, the screen protector is so much uglier that it distracts you from the case. The film they use expands with the heat of your pocket and creates bubbles in new places each day. It makes the iPhone appear to have contracted plague. I suggest you toss the supplied film and buy a ClearTouch Anti-Glare Screen Protector by BoxWave. The combination should work well.
I give it 4 stars because I live in a marginal reception area and I like the boost it gives me. And no one can see it when it's in my pocket.
