Excellent value for money. Only downside is the collimator needs to be calibrated before you use it. Do not worry, this is very easy to do- check out YouTube to see videos on how to calibrate it- it literally takes a couple of minutes once you make a calibrating jig- I just used a spare pool fence hinge I had laying around, but there are lots of ideas on YouTube. There are three silicone plugs (silicone sealant) that need digging out before you can access the adjustment screws to calibrate it. Unsure why the manufacturer doesn't fit actual rubber plugs/bungs in these holes rather than silicone sealant. A highly recommended bit of kit that is a must if you own a Newtonian Reflector Telescope.

The laser arrived today, and the first impression is not so good. The laser works, but it came so bad out of alignment that its impossible to adjust or collimate the telescope. Its really frustrating. I have adjusted the laser via its 3 collimation screws. But a normal user or a beginner will not have a good time with this product, and can cause more harm than good to your telescope. I guess you get what you pay for. For beginnera I rather recommend a branded product that comes pre-aligned and centered.

Arrived well packed. I immediately checked it for collimation, and it was excellent, less than 3mm eccentricity at 5 metres beam distance. Variable led light switch and ease of battery replacement make this a good cost effective tool for the amateur astrophotographer.

Good cheap alternative to an expensive one but had to adjust the laser direction so it was acurate. Other than that all metal body. Does the job once collimated

The Collimator is better than expected, made of light alloyed and tough, better than the one I had that was plastic
