I was very nervous about getting this engraver. I have experience with the bigger name brands and it was a mess and waste of supplies. Kentfaith did not disappoint. It took me a few to upload drivers and program to my computer but it’s fairly self explanatory.The best part is that it will shown you exactly where it plans to cut so you can position your item as perfectly as you can. For the price I paid it more than excelled in what I wanted and needed.The program it self is simple and I do need to make some designs in another program or app and the upload the picture. The large monogram showed up pixelated on the program but when it engraved was smooth lines and nice detail.While this is portable, please please use it in a well ventilated area with a fan near pulling the air away. Because it is portable I am able to take my work to the porch and easily work on it there.The mobile app…. Is less useful. Mostly because it won’t preview, meaning show the exact area where the laser with engrave; so boo for that.As for height adjustments, I bought some not jenga at the dollar tree and glue heights I needed and it works fine~The work area is small but if you are new and just need something to learn on and eventually keep for quick small projects this is definitely worth it.Engraving time… about 5-8 minutes on my pens. And the big monogram with is nearly the full working area for the laser…. About 2 hours. Yes it’s a bit of a long time but considering that I couldn’t get the name brand to do this nice and smoothly, I’m more than happy with the times.I am primarily working on bamboo, and the color of the engraving will vary on the wood, but each is well done and nicely finished. So if some engraves look lighter or darker , it simply the wood itself. I was worried about people not liking it, but most people were so happy getting a personalized item, they didn’t remark on burn variance.I hope this helps you if you really want an engraver but don’t know where to start. While the engraver isn’t exactly plug and play, considering cost and the fact you don’t have to have a subscription to use the program, I find it more than balanced in the work I have to do manually and what the engraver accomplishes.Happy engraving with all your projects~
