Though I'd best weigh in...
25 September 2023  | 

Puns aside... Its does make a difference to have a proper counterweight as appose to a dumbbell weight or an old shoe hanging off the end of your bar so do yourself a favour and get one. Oh and get one from FLO because they'll have delivered to you nice and quick and you'll get to leave a silly review like mine.

IOptron 2kg counterweight
16 November 2022  | 

I use it with an AVX mount, it fits perfectly. I now can balance the mount with a lightweight Redcat 51 as I live at 21 latitude and the original counterweight hit the lat knob. Thanks FLO for the fast delivery and the help about this product.

CEM26 Diet
29 July 2022  | 

I needed a smaller counter weight for my CEM26, the supplied 4.7Kg was just to heavy.
Why so much for a lump of iron? Well the machining of the locking screw is first rate, with a brass clamping bush so as not to damage the counter weight bar.
FLO delivery and packaging 1st rate.

Ideal for the smaller scope
11 February 2021  | 

Following recent purchase of Ioptron GEM 28 I found that the stock counter weight was just too much for the small evo guide 50 ED. This is ideal. Prompt dispatch also following easy purchase process. Thank you FLO

What can I say
30 November 2020  | 

It's a counterweight. It was heavy, but not as heavy as some.... I mean it's a weight, so I guess you expect that. It has a hole in it, like a doughnut, but don't try to eat it. I now need to see a dentist!!

In all seriousness, it does the job, original item, no complaints - now I can view the universe.

iOptron 2kg Counterweight for iEQ30 / MT / AZ Pro / ZEQ25 / CEM25
07 June 2020  | 

I use an extension bar including this 2kg weight for my CEM25P mount and it helped me achieve balance with a large Bresser Messier AR-127L telescope (8kg).
