They are quite interesting, technically a bit more efficient than usual engines. However in practice you end up having more problems with those as it is very hard to cope with the heat in the centre piece, while rocket nozzles can radiate heat outside.

Tim Dodd did a really good video on them. It explains what they are and compares against traditional rocket engines.
That is a great video. Thanks for the link!
You're welcome!
