I was going to bump this thread with my experiences of the last few weeks.
I am very impressed with blocks, I also have no problem with the latency and if you take into account that the FAQ says not to use non wired headphones, its fine.
Noise is not great but the new soundpacks at least make it more flexible but itās crying out for a mixing page where you can alter volume and i think it needs a way to go to sounds directly not scroll through them.
Also the quantised rhythm parts (groove kits) seem to be slaves to a clock so if you press on an offbeat, you have to wait for the next beat for the drum part to play, I suspect this is where most people get the unacceptable latency issues.
Having a small bluetooth MPE controller is lovely for using with apps on an IOS device, and I was really interested in using it with my MIDI sequencer (Kilpatrick Carbon) as an alternative to a keyboard, where you just need to input notes and the sequencer will take care of the rest.
Unfortunately my Carbon seems to freak out when you put a USB3 device into the USB host port, but I hope that the upcoming Blocks dashboard might allow you to limit the data that the device spits out. ( similar to configuring Rise to single channel mode)
I managed to get mine at a very reduced price, So I am not sure I would be so forgiving if I had paid RRP for it, YMMV
