Update #2Well, the seller contacted me, and very politely offered to send me a whole new engraver, no need to return the first one. I received it, and it had its set screw, and works. I’d give the seller 5 stars for the customer service. I give the engraver a 3. I think it will be fine for marking belongings in case of theft, but dont expect perfection in appearance. Maybe it’s partly me. Maybe with practice I’ll rate it higher.Update 1: No WONDER I was confused!! A friend looked at it and said there should have been a screw screwed into the hole that I was putting the Allen tool inside! There was no screw there when I pulled it out of its packaging. The Hardell company has reached out to me to see if we can resolve this.“The directions for inserting a tip into the engraver are too vague. The allen wrench supplied does not seem to fit into the screw to loosen the tip, and the directions don’t say or show how one is supposed to be able to retighten the screw, since from what I can see, the back end of the tip would be covering access to the screw behind it. If someone out there can post a video showing the tip insertion process, I’d appreciate it. If not, I’m going to have to return this item. I bought it to engrave a present for Christmas. I won’t be able to if I can’t figure it out. I’m rating a 1 star for vagueness of directions. If I find out how to use it, I’ll re-rate.”

Works well

As advertised, it has 5 speeds but they are too closely matched to make any difference. Low speed and a light touch allows reasonably fine etching of steel but a lower speed would have been nice. Still it works and the tips don't dull quickly.

Good engraver for small items. Wouldn't recommend for extremely heavy items that might dull the engraver. So, far so good with everything as far as comfortable to hold and use.
