I use it to get sound from a TCL 55 6KS TV to an old amplifier (dolby prologic) and it does its job without disconnections and problems

Decent for non-demanding users. It does not produce stereo sound. After a small drop, it stopped working.

I also have the tp-link, this one is 10 times harder to connect, there is no significant difference in sound quality, even though it is a newer Bluetooth protocol. The only positive is the RCA, but this also does not offer better sound compared to the traditional plug.

I give it a 4 because it has a difficulty in connecting two different phones and because sometimes it only connects on its own and I don't have sound on the phone. Other than that, it is very good.

You need to press the button for a few seconds while on the source device, no one is pairing it. This is not always easily achieved.

Purchase on 29/12/23, first test as soon as I received the product, very good both in terms of sound quality and installation. I don't know about vacations because I haven't used it for a long time, that's why four stars.
Something that impressed me is that I found it in the Bluetooth 5.0 category while it says 5.1 for me, also in another review photo the box says 5.0.
Maybe it's the new version.
I also include photos.

At the 20 euros that I bought it, it is excellent. It connects quickly and steadily with two devices. The sound quality is good, comparable to more expensive ones. I also have the TP-LINK HA100, which has good sound, supports more devices simultaneously, and NFC, but the Bluetooth is constantly searching, resulting in the whole neighborhood connecting to it and instead of listening to music, you hear the neighbor's Viber because they found an available Bluetooth and connected to it, or it connected once by mistake and every time it is in range, it connects whether you want it or not. I don't know how long it will last, it is constantly on, just like the TP_LINK that worked for over five years until the whole neighborhood decided to connect to it. I recommend it to anyone who doesn't want to spend over 100 euros on devices, with Bluetooth 5.1 and APTX, it's worth it.

A good choice to upgrade a Hifi system, quality construction connects directly with the smartphone and has satisfactory range, unfortunately I have not managed to connect a laptop despite all the attempts.

About two years of use, everything works perfectly with a Denon amplifier and Q acoustics speakers. It transfers signal from my mobile to the amplifier, I listen to Spotify in my professional space for several hours every day. With a change of mobile to a newer one, the sound quality improved significantly. Choose this version with Bluetooth 5 and APTx

In 30 days it simply stopped working. It connects to the device but doesn't transmit sound. Money wasted. I replaced it with TP-LINK Bluetooth Audio Receiver. Cheaper, better brand, and the product is stellar.

Perhaps the best in its category. So far, it works flawlessly and with good sound quality. I highly recommend it!

It works fine, the sound is good, but I can't connect it to the TV

Good phase. However, it does not have Apple's AAC codec, in terms of its connection, I wouldn't say it's lightning-fast, and it doesn't have NFC.

Very good!!!

I have it for a month. It has a great range. It has worked for up to three hours continuously without stopping or disconnecting so far. It connects to the mobile very quickly. 4 stars because it loses some quality compared to a direct wired connection (not a huge loss but it does lose)

I connected the projector to the amplifier via Bluetooth and in terms of impressions, the sound quality is very good, with negligible or no delay. However, sometimes (once every 2 hours) it does something like the sound stops for a second, not a disconnection but more like a slight delay in transferring the sound, but this may possibly be due to the projector.
