Amazingly small, pretty well made. but the price to pay for small size is thin plastic that feels fragile, and a bit flimsy finish. Instead of cold shoe mount, receiver has a cheap clip, like cloth-line clip. it kind of fits into the shoe mount of your camera, but is not very sturdy. It looks nice enough, but overall durability is a bit iffy. Also, sound quality is good, but has a bit too much hiss/noise in the background. As much as I would want to give it 5 stars, I can't, because I know it will develop some problems soon. It is not my first system and I am a pro, so I can compare. If you want something really strong and durable - this one is not a Rode. But it is one of smallest and lightest systems, which I need for travel. So, for me it is kind of ok. Wish it was a bit stronger and less hiss.
Works as expected, audio quality is great. Using these for real estate tour videos where I walk around and am filmed in 3rd person, or sometimes for short interviews.
