This is my 3rd and last email to Toolz Customer Service(the last 2 emails remain unanswered).I just returned the second defective RT 7610-5... Toolz should advertise this unit as a 6 or 7 or 8 beam laser (Laser Flares all over the place) depending on the particular unit received. You could also rename it the "Searcher" (searches, searches & searches for level)... better yet the "Searcher Laser Show".I have a suggestion for your spreadsheet, quota-based management... buy a copy of Deming's book "Out of the Crisis" and learn his simple, but eloquent manufacturing philosphy "Quality = Productivity = Lower Costs".How do you people justify dumping a defective laser product (a laser represents precision) on the market???... where is your quality assurance???... or maybe all you care about is getting "xx" number of gizmos out the door to satisfy some bean-counter's quota???How embarrassing... Hey boss, which laser point do we mark?? (I think I'll spend a little more and look at PLS units).
