" ... The manufacturer inserted glue into all of the calibration holes, and then put a laser warning sticker over one of them. ... Bottom line, laser collimators are only as good as their correct fit to your telescope. ... So if it worked, you could collimate while looking at the adjustment screws and the red dot at the same time, and not have to go back and forth. ... "
" ... The laser does not stay on. ... "
" ... Not only is the laser not collimated, the 3 adjustment screws are hidden behind rubbery material that is difficult to near impossible to dig out. ... "
" ... This collimator fits loosely in the focuser. ... The collimator’s collimation itself was fine out of the box, but it just fits too loosely in the focuser, along with its 2 inch adapter, both have poor fit up tolerance. ... "
" ... There's two little rubber stops and a third one under the laser warning sticker covering the allen head adjustment bolts. ... Took me a good 15-20 minutes to get it tuned in once I dug out the rubber covers and made a mount for doing it. ... "
" ... It isn't calibrated properly out of the box and the 3 adjustment screws are buried under rubber cement that you'll have to dig out. ... "
" ... It's not collimated out of the box and the collimation screw holes are filled with rubber. ... Why would they fill the collimation screw holes and make them inaccessible? ... "
" ... As you turn it you'll see the spot doesn't stay centered at all. ... AND they put glue over the screws to collimate it. ... "

" ... Great product, very easy to colluminate my 1960s vintage Edmund 6” reflector. ... "
" ... Well after trying collimated the telescope with out one of these this was quik and easy. ... "
" ... I use this for my newts (much easier than the old style Cheshires as you can adjust the primary cell without looking through a sighting tube- you can see the laser on the 45 degree target from the butt end of the scope. ... "

" ... Since I had to destroy the rubber caps in order to get to the adjustment screws, it didn't seem right to return it. ... "
" ... I had to dig out the rubber inside the three screws to try to align it. ... "
" ... I had to remove the silicone glue from the set screws to adjust it and now it is dead on. ... "

" ... I did (Celestron 127EQ) and after learning that I had to remove the correcting lens from the scope, the laser worked much better. ... "
" ... Also was handy to check out a used reflector telescope to make sure the mirrors were ok and it was possible to adjust it. ... "
" ... A word of advice--some "Newtonian" telescopes are actually Bird-Jones telescopes, which have a corrector lens in its focus tube. ... Otherwise, I've found it's still possible to do a decent collimation without removing the lens, as long as you can still see the "blob" on the collimator. ... "
" ... Great help in collimation, or aligning your telescope. ... "

" ... Decided to use so I put in Amazon Basic 2023 3V coin battery and it is dead. ... Tried other working batteries and nothing. ... "
" ... Worked for 5 minutes now it won’t turn on, replaced battery and still nothing!!!!! ... "
" ... When the battery died, I discovered that the cap that must be removed to access the battery, was cross-threaded and forcibly assembled, making it impossible to remove the cap without destroying it in the process. ... when the battery dies, which it will eventually, then the laser doesn't come on. ... And if it is impossible remove the cap used to get to the battery, then the battery can't be replaced. ... And if the battery can't be replaced, (see where this is going?) ... "
" ... Came uncollimated, in an smashed box and the battery wasn't working. ... "
" ... I replaced battery and it did not solve anything. ... "

" ... The 7-position brightness adjustment is a nice addition from my old one which just failed. ... "
" ... Can dim the brightness because mirrors spread the light and makes it easy to adjust the beam from the mirror back to the laser hole. ... "
" ... But I can tell when the light pattern is centered by pure brightness of the scattered beam on the back of the target . ... "
