I've used quite a few different models of blink lens hoods since I've been welding and I've used the Esab model.....but the best speedlens hoods, Hands down are SPEEDGLAS. I have the speedglas XL, APC-V, APC, 9000X, and I use them all the time... I let a couple of the welders I work with use them on occasion, but they know how I expect them to treat my hood. One of them has the Huntsman auto view, and he hates it compared to my speedglas.
The XL I use for my mig welding, the APC's I use for tube tests, and the 9000X I use to air arc.
No doubt about it the older model speedglas' are the best....Hornell needs to bring back a three sensor lens.....get rid of the two sensors, or make a four sensor lens.....
