I wasn’t quite sure what to expect when ordered these but was so happy and kind of shocked when arrived.They are amazing quality.They come in own fitted case there is very sturdy and strong handle plus extension to go on handle and lots of little accessories.There is everything you would need to open and replace battery in I phone ( I know this a previously purchased kit to replace I phone battery) At other side of case are all the screwdriver heads and there is a head for everything.It is a presision set so a lot of head are for tiny screws but there are also few heads which are a little larger and could handle more everyday tasks.The heads are held securely in handle and are magnetic so hold onto screws.Great set at amazing price
