Are you planning on taking your phone apart? If so do you have the skills to do so?
There are lots of these tool kits out there, of widely varying quality. If you really do have a need/use for such tools you should do some online research to find the ones that are the best quality-wise and most compatible with the device you want to take apart. Better to order a set of good ones and wait a couple of days than to buy the not-so-good ones in the store.
