I use an Ixon air bag vest which is electronically triggered, it’s very good and yes I’ve tested it 😀
The Ixon along with the held, furygan, RST and klim systems use an in&motion control system which is subscription based, approximately £100 a year. Dainese and alpinestars also have their own vests using their own control electronics which are not subscription based. All systems work well and if you’re using it purely for road use then I’d pick either of the alpinestars or dainese systems. For track use I’d pick one of the in&motion based systems, solely because the compressed air canister is user serviceable so can be changed at track side, whereas the alpinestars and Dianese vests are not user serviceable and have to be sent back to the manufacturer for service and regassing.
