After 10 months of use I can say: incredibly small, excellent sound, and absolute flexibility.

I have owned it for a little over 10 months and it is truly a value-for-money purchase! In my opinion:

Pros:
1. Size & Weight. They are tiny (coin-sized) and weigh only 9 grams. They do not pull on clothes at all and are completely discreet.
2. Combo, it pays off because of the flexibility. The Combo version is the best choice. It includes receivers for everything: Camera (with 3.5mm), iPhone (with Lightning), and Android/iPhone 15+ (with Type-C). You can connect it anywhere without buying extra adapters.
3. Very good sound quality. I am not an expert, so I judge it only from what I write, and it really is clear sound without losses, ideal for vlogging, interviews, or videos on social media.
4. Great battery life since the carrying case is also a charging case, it is beautiful, automatically charges the microphones, and offers up to 40 hours of total operation.
5. Mounting: The magnets are very strong and the mounting options (clip, neck lanyard) provide solutions for every outfit.

Cons:
1. Noise Cancellation is useful, but it can sound a bit robotic at maximum settings. It is better to keep it turned off and make any corrections in the video editing software, although inside a car with the windows open and wind due to the car's movement, the sound from both microphones was nice and that robotic characteristic was almost nonexistent.
2. It does not have internal recording nor a port for an external lavalier.

If it helps anyone, for use with a GoPro Hero 12 with the Media Mod attached, you need to use the camera adapter and the SRS to SRS 3.5mm cable included in the package. Also be careful with the mounting because although the media mod has coldshoes and the camera adapter from the combo has a clip that fits into a coldshoe, on the media mod it needs quite a bit of pressure but be careful so it doesn't break. I slightly opened one of the springs so it fits more comfortably.

• Very good for its price, exceptional recording quality, although it is a step below the equivalent Top models of Rode and DJI but to notice it you will have to make a direct comparison. Also for half the price and the conveniences offered by the kit, I would say it is unbeatable!
• The package includes 3 Receivers, one compatible with iPhone (lightning), one compatible with USB-C and another one that connects with Jack 3.5 but also with USB for cameras and computers. The 2 microphones are slightly smaller than a two-euro coin and each has 3 magnetic adapters. A simple magnet, a magnet with a clip, and a necklace magnet so you can wear them even without a shirt. The package also includes 2 "dead-cat" windshields.
• The range with obstacles and generally in a space with many electronics is not huge, somewhere after 10-15 meters interference starts. Clearly greater in an open space without interference! • The battery lasts many hours, it did not run out after a 6-hour shoot, however I had not yet connected the application to see at what levels the battery had dropped. Charging is quite fast and because the case functions as a Power-bank, it makes me believe that the 40 hours of recording claimed by the manufacturer are true and may even be more.
• For anyone who wants to work with both microphones on separate audio channels, it can only be done through the receiver for cameras with the press of a button. This cannot be done with the receivers for mobile phones.
• The noise reduction is very good and I would generally recommend it to be the only Mode you will use since the normal one picks up a lot of noise from the environment.
• Another clarification you need to know before purchasing is that the microphones and receivers do not have any memory or storage space for recording, so if someone is looking for something to store backups, they will have to go to Rode or Dji.
