Have been rolling this for the last 4 months. Pretty spendy but one of the cheaper respirator mask setups (got it for about $1600 through trade deals and a special sale). Definitely recommend if you're welding often as I do a decent amount of heavy fabrication at work, usually a few full days a week so it gets a good workout. I've only needed to charge the battery a handful of times and the filters are barely worn in.
I've never had any issues with sore eyes or arc eye in the last 5 odd years I've been welding and and my previous hood was a ASAB Sentinel A50. Only reason I upgraded was due to work hookups and also I've had galv/zinc poisoning in the past (which is fucking horrible, really bad fever and aching muscles for about 1-2 days) due to fumes. The only real issue is with it being a little bulkier with the lines and belt, it can be pretty difficult with work on site getting into tight places especially if I'm climbing under track gear or such on a bulldozer or what have you.
