Review on 🔴 SVBONY SV121 Red Laser Collimator for Newtonian Dobsonian Marca Telescope with Adjustable 1.25 inch Collimation Eyepiece and 2 inch Adapter by James Womble

I first tested this laser on a V-Block and found it to be somewhat fuzzy and unusable in the condition it was shipped in. I reported this to the seller and didn't see any collimation screws to adjust. The seller emailed instructions stating that the laser was fine calibrated at the factory, not adjusted, and that the collimation screw was under a label on the laser housing. This is the new SVBony Laser Collimator, marked as adjustable on the box and supplied with an Allen key. Upon closer inspection it turns out there is a removable ring in the center exposing three hex collimation screws, product instructions via email and SVBONY seem unaware of this! I have decided to return the item. Update SVBony sent a replacement which arrived in perfect condition and well collimated. The laser works very well on my 18" Dob. SVBony's customer service is top notch and very responsive and I am sure they will update the manual in the near future.
