### ⭐⭐⭐⭐⭐ Recommended

Worked as intended

### ⭐⭐⭐⭐ Finally one that works! (although setup could be better)
*by S***C on 23 March 2025*

So have tried a few of the cheaper ones and I was having an issue with the cheaper ones as they would just keep dropping off (after reading a few reviews looks like they go to sleep - kind of defeats the purpose as it needs to be on 24x7) so though would give this one a try and BINGO - it just works - stays on all the time so no issues there - very pleased with it... Have to deduct 1 star though for setup... whilst the "cheaper" ones have the edge in setting up over the Broadlink [the cheaper ones seem to do bluetooth setup so are easy to add to the apps] the Broadlink ones mandates you *HAVE* to connect to 2.4Ghz WiFi - have you ever tried that? (You basically can't disable 5GHz on most smart phones and indeed routers!) so managed to finally get it to go into 'AP' mode [instructions are not very forthcoming for that! it's like mentioned in a small paragraph] also the Voice Intergration [Alexa] setup is a little counter-intuative... In the App there is a 'link' button but never seems to be enabled (tried on both an iPhone and Android device) - turns out you have to go into the Alexa App and enable the skill which then links your account - found this "mentioned" in the manual - so why have that button in the App? at least get it to display a little help and maybe launch the Alexa App... But overall, would recommend
