I got these at the start of the year and waited a while to see how they worked out. For recording, they are excellent and I had no problems connecting to my PC. The 4.5" speakers have enough power for home use and can keep up with a guitar amp at home volumes. The cables for connecting the speakers were a bit short for my needs so I bought some 16 gauge wire and that was adequate. The slave speaker is 4 Ohms, 25 watt so up to 25 feet, 16 is fine. If you want longer, go with 14 gauge.
The Bluetooth connection is simple and convenient. It turns these monitors into something very convenient and I wish more manufacturers would incorporate it. Being able to connect your phone or tablet is just fun. Something I think matters in a product in this category. No cables to listen to music on your phone, no messing about or booting up the computer.
There are plenty of connections on the speaker and they will likely suit most home users. These are not high end studio monitors. For home use, this is actually quite a positive and part of the reason I wanted them. Professional studio monitors are extremely directional. These are, as all speakers, somewhat directional but they can fill a small room and be treated as a nice set of home stereo speakers. That may not suit pros but, if you are a pro, you will already know that and be looking for something specific. For music enthusiasts, creators and general home use, I think you'd be hard pressed to find a more compelling product. I do fancy the subwoofer but honestly, they sound good enough for what I use them for and I don't really need to shake the whole house.
So, I'd definitely recommend them for home use and general listening. They would be good for a gamer that wants something better than your typical PC speakers, these really are a massive upgrade at a reasonable price. 4.5" is generally a good place for home use and that quality vs cost sweet spot. If you need something for the pro studio, these aren't that but you'd already know that if you did. More than enough for the vast majority though. They look good, sound good, work well, have Bluetooth, lots of common connections and all you need is some speaker wire if you want to separate them across a small room for a small stereo speaker system. They tick a lot of boxes and deserve to be praised.

Value for money
These monitors look and act like 1990s PC speakers. Do not expect too much out of them. Nevertheless it great value for money. Going to add Sub8 in the next month for a bit of more bass.
