And Now, My Opinion:

A combination of ergonomic grip and light weight make this extremely comfortable to hold, even for extended periods. The supplied lanyard adds extra security too.

I have arthritic shoulders yet I can gaze at the stars with ease.
Note the indented focussing ring. It's smooth but not loose. It needs to be though because practice is needed to get focus spot on, it's extremely sensitive and only needs TINY adjustments!

The eyepiece can be set for both aided and unaided vision by simply twisting it.
Set for naked eye viewing.And now for spectacles.

It comes with a lovely case which has a belt loop. There's a lens cloth too.

Using The Monocular For Astro Photography.

This shows the monocular attached to a mini tripod by using a customised Celestron basic phone adaptor.
Add a Bluetooth shutter to prevent vibration, attach your mobile phone and it's ready to go! 

The light weight of the unit means that the whole rig is well balanced.

The Proof Is In The Pudding!

The image of the Moon below was taken early evening with my phone at maximum magnification.

Pretty impressive huh?

Summary.

Likes.

Really comfortable to hold, even for extended periods.

Crystal clear image with minimal distortion etc.

That lanyard!

Works well with a phone mount.

Dislikes.

Focussing is extremely sensitive until you become acclimatized.

For stargazing, the field of view isn't that large.

Images could be a little brighter.

Conclusion.

The unit's size and weight mean that it's perfect for popping in your pocket or bag whilst out and about. It is ideal for wildlife spotting and is also a fantastic o.t.g. device to use for checking out a clear night sky. Considering it's humble price, I think you will be amazed, as I was.
