I am sorry but I personally have no experience with Bodyguardz what-so-ever. I have used an invisible shield on an iPhone, but it was a very short time. However, I have a GadgetShieldz installed on my Tilt 2 and had one on two of my Fuze's. I think for the price the GadgetShieldz has been a great investment, but do be warned with any of these the screen (I imagine the other two are like this) will have a "drag". With the stock screen protect your finger fluidly slides around. With the GadgetShieldz I do tend to apply more pressure because my skin drags with the surface of the shield, but my screen is still very responsive and works just as it did without. I use the Swype keyboard for my input method and once I adjust to the shield it was like normal. Using the stylus is a bit harder because you cannot simply drag it, but if you learn the right amount of pressure needed this is not an issue.
The back is still kind of slick but better than stock, and I feel less worried now setting my phone down not so scared that it will scratch up that shiny back, ya know!
At 6.99 I recommend the product! There was a 15% off code on my thread also.
Edit: Please check this thread
there is a 15% and 20% code posted! Enjoy!
