Review: Great Product - Great product, just watch out for the protective film on the mirror surface, hard to spot! Very quick delivery, brilliant price and performs very well. Really happy with these mirrors.
Review: Wow, what a difference they make. - I replaced my Omtech standard mirrors with these and have to say I was sceptical at first, after 5 years I decided it was time to remove the originals and inspect them having cleaned them with alcohol wipes in situ previously. On removal the originals were in quite a state. I fitted the new ones and also aligned the mirrors, the difference was incredible, cutting could be done with less power and at higher speed, these mirrors were a total game changer and well worth the cost.
