If you can wait, I would wait till I get the metal version in, that way Ill be abl to compare the signal strength side by side and comment on the integrity of the case. I personally feel that if the metal version works well with the cell phone's signals then it is the superior option for maximum durability and strength. Reading the reviews of the genuine lunatik, Im just not sure its worth the price, I mean most people here in Canada are getting hit with $150 + $65 import tax from UPS. Thats just too much for a phone case to me. Now the knockoff plastic version feels like the plastic they used is a little on the weak side (at least the one I got) but I think metal one may hold the solution for a strong yet inexpensive case.
I used to use the Otterbox defender and I switched because I as well got sick of the screen. I can say that the knockoff version has the nice glass screen and it works flawlessly. I only have the defender for the iphone 3gs but the difference is night and day, even the knockoff version of the taktik is absolutely mint when it comes to screen clarity and response. If you're not getting deployed too soon, Id wait for my review of the metal version and go from there. I should receive it within the next 5-10days and I will post pics and review immediately.
