Good but note for Macbook Pro Pros:
Great laptop lock I got this lock after getting the cheap $8 Noteguard branded one from Amazon. That lock was fail on all level. If you’re trying to decide which lock to buy, you can read my review on the $8 one by looking at my other reviews.
Excellent protection for your laptop, etc. I owned a ‘cheap’ laptop lock before getting this. (It was around $15.) But after getting this, I saw the reason for the difference in price: the mechanism that actually locks to the PC. My ‘cheap’ on you could pick off with a small screwdriver or knife. These ‘good’ ones— you won’t get that lock off without breaking the laptop or cutting the cable.
