It took me a bit practice to learn aligning the motor axis with the polaris, but after then even 135mm focal length is possible with 4 minutes of exposure without any stars moving in the sky, I find it really awesome! It's small, easy to handle, and the battery lifetime is also great.
5 stars from my side!

Does what it says on the tin, I find with the basic lightweight setup you really are best leaving it for shooting wide, I tried up to 70mm and while the stars were still sharp at 2 minutes, the level alignment wasn’t great.
It can be made easier with the V plate as you do need to start off level before pointing upwards. Otherwise your framing will become off after a number of shots.

Great piece of equipment, compact and light, does what it says on the tin

Works perfectly, even 400mm focal length is possible for 15 or so seconds. V mount highly recommended. Not so sure about the phone mount though. Found it much easier to just put the phone straight to the back of the device. Phone mount has a tiny bit of play so that you can not be absolutely sure, if it it’s really exactly parallel to the rotator.

MSM mechanics r smooth, robust, functionally excellent & high quality. My quibbles r with the included instructions where pictures r too small to really illuminate details and written text sometimes obscure.MSM's accuracy relies completely on accurate orientation and in the Southern Hemisphere that is problematic. The actual SCP has no bright marker Star. Photopills Night AR accuracy depends on phone compass/GPS accuracy and other methods r all empirical. The Laser attachment is pointless (😉)here.

It's good for me.

I'm really happy with the ease of use of the MSM. It's very portable as well. For shorter focal lengths like widefield 14-24mm lenses the polar align using the laser pointer is accurate enough and done in less than 1 minute.

Finally got a few clear evenings and tried the MSM Rotator with polar scope and laser. Super easy to set up, find Polaris and align. Rotator seems to work well, minor star trails up to 30 sec. So far impressed! Will upload photo.

Haven’t had a chance to use it yet but will shortly! Thank you guys I think looks great.

Small, compact, easy to set up! Just waiting for a clear night!
