Anyone using Coretech Photon wheels? Are they any good? Opinions

im not too sure which specific wheels these are, but personally i never buy wheels which have a 'core' because from what ive seen they are a rip off and dont last as they tend to split.

See loads of people riding them at rampcity, aparently they are amazing for skating park/transition.

I had some Autobahn cored wheels and they were the dogs bollocks, but thats probs because they where Autobahn's and there great wheels anyway.
