As a few people have mentioned, it did the job.
I had to be quite particular when doing the cutting because the Sim card did move a little in the cutter, if it had not been lined up by myself then it probably would have damaged the chip. Cut was a little rough, so I had to clean it up a little. Tried it with one of the enclosed adapters in my Galaxy S2 afterwards and it worked fine. Inserted it into my Google Nexus and it worked fine. All in all, good for the price, just be careful while cutting. I purchased this for work purposes, and I feel confident I will be able to cut a dozen or so sim cards with it.
