Pros and cons

Pros

Low-profile positioning can keep a microphone out of the way of a monitor.
Two thread sizes are supported through the 3/8-inch connection and 5/8-inch adapter.
The stated 1.5 kg load limit and 74 cm horizontal reach provide useful reference points for checking fit before purchase.

Cons

The 1.5 kg maximum load rules it out for microphone-and-accessory setups that exceed that weight.

What to know before buying

Listing details to confirm

The title gives 38 cm +35 cm, but feature text states up to 74 cm horizontal and 35 cm vertical extension. Check the selected listing and confirm the microphone's weight, thread and desk thickness before buying.
