Simple to use,

This review is from: Micro SimCard Cutter & 2 Free Adapters - Ideal for iPhone 4 & iPad (Wireless Phone Accessory)
This cutter is very easy to use and it cuts correctly. I did have to file it a little because the edge of the SIM card after cutting is not very smooth but after that it fits the slot. I have only tried it once.
The adapters I have not used so cannot comment.
Good for the price.
