Like you I read the reviews and was a bit disheartened by people saying this crown was cheap only good for a few uses etc. However I only had to use it twice so I decided to take a chance. Well I've used it 3 times and I have to tell you guys it works great. No, you probably won't "pass it on to your grandkids," as another reviewer said, but who on earth passes stuff like that on anyway? I mean how many times do you really have to cut a 4.5" hole? Probably not often. And if you do this regularly, then don't be a cheapskate. Invest in one that costs $50. it works great I don't expect to use this product again but if I do I'm sure it will work great.
