This works as good as the day I bought it -- perfect. I simply have two from buying a new telescope. Note the base still has the 2-sided tape unused, as I secured it to my Dob with bungee cords. See the tiny cut in the tape -- it will have no impact on mounting. This Telrad is about 10 months old. First $35 takes it. I'll pay shipping to US only. Canadians will have to add $7.
