We ordered the 200W "single pipe type B" jet and I can say that they work very well! First off the supplied high pressure hose is top quality (nice hydraulic crimped ends, 3/8" ID for great flow, real CGA-320 fittings without needing messy/leaky extra adapters and seals). Fits USA Co2 tanks perfectly! (a lot of machines from China come with poor quality hoses that costs a lot of extra money to replace later) As far as co2, make sure you order Siphon tanks for use with these, or else you will be running your co2 tanks upside down which is not recommended). The DMX control on these is super easy (single channel command to open the co2 valve), and it is very responsive with no delay. The valve inside is great quality and does not freeze up (even with 4 second co2 blasts). Connectors are 3 pin XLR for DMX control and powercon for power (120V), very standard. So far I have put a few hundred lbs of Co2 through these and have not had any issues. They are very small and easy to hide on stage. Most importantly the customer service from VONZOER is excellent, I bought from them (and highly recommend them) as they were very responsive and helpful in answering and questions and getting these units up and running. Gas consumption rate will depend on your siphon tank valve, but a good rule of thumb is about 1lb per second of operation. I hope you find all this information helpful (it took a lot of trial and error to find a quality machine at a good price).
