KARI has been nothing but great , she gave me the best price on alibaba that I could find and she made delivery easier for me , I trusted her and it arrived not just in time but it arrived 1 day early , 1 thing I loved about Kari is that she told me “ any problem you have , I will solve it “ and she has solved it … even after the machine arrivle she connected to my computer so she can set it up for me … I still don’t know how to use it as an starting to engrave … but as soon as I start my deep engraving in fire arm things I will be posting the quality of work it does and if it’s worth buying as of right now presentation and all is great but now the test of quality is up next ……. please feel free to follow up with me at jjonathan.lara@yahoo.com … I made this email especially just to answer replies to this review
