Has anyone here bought these mirrors off ebay?

I am debating whether to order this set or 3x of the MO ones from LightObject. Wondering whether the LightObject ones are of better quality and worth the additional ~$35.

I have bought a k40 lazer engraver from China cannot install software that came with it any suggestions please

I have had my eye on theseor a while,yes they are worth the extra money.if i didnt have lots of spare mirrors i would buy

You have to open the rare. File found on there disc… took me awhile but finally figured it out

for reference to anyone that sees this post - I bought these mirros and they are just okay. They came a bit dirty. I havn’t compared to the lightobject MO ones - but if I were to buy again I’d probably get the lightobject ones.
