Ok, so I have used this for awhile now and have a couple complaints. First... the tension adjustment knobs need constant adjustment or it will "Lid Down" on you. Second, trying to push the Lid up is annoying at times cause there is nothing to grip on to so i end up scratching up the front lense lol.

Sometimes i try to lower the hood only to realize its already down.
I walk around with it on the whole time in at school/work since its so light.
People constantly want to see it.

Will buy again unless I end up using someone else's hood and its better somehow.

Works great and is a revelation after cheaper auto darkening helmet. In normal mode I can work without raising the visor, seeing everything clearly. Darkening is widely adjustable and also works great.
I did sweat a lot on mine one day (working in the heat of Cambodia) and it went a bit funny for a while but after drying out it performed fine again. Will have to be careful in the future.
Head adjustment is massive and very comfortable once tailored to your head. Rock solid when in place.
Comes with 2 clear and 2 yellow outer covers and some inner covers too. Also comes with bag and bandana. These are standard with the helmet although some places advertise in a way which makes you think they are giving you them as an extra (not this supplier though)

Only negative point i would make is that you have to be super careful how you put the helmet down so it doesnt roll onto and scratch that futuristic front lens

It's unreal how clear it is when welding with the clear lenses, you see everything as if you didn't even have a helmet on. I had to adjust the shade higher than I usually have it with other helmets due to how clear it was. Felt like I was learning to tig weld all over again.

The head gear is great but takes some trial and error to get it how you want it due to how adjustable it all is. feels very comfortable once you have it dialed in, the back strap has a nice pad that cups your head and doesn't feel like you're tightening a ratchet strap around your head like other helmets do. The helmet stays up until you flick your head, I haven't had it fall down on me unintentionally yet.

The touch screen is super responsive, almost on par with an iphone honestly. adjusting the controls are easy and the preset function is useful.

The grind button takes a good amount of pressure to press so you'll have to hold your helmet in place with one hand while you press the button with the other.

The box came with a nice padded bag for the helmet, welding do rag, and 6 extra lenses which is nice because they seem to be pretty expensive.

This helmet oozes quality, well worth the $300 price tag.

I love this helmet. I couldn't decide between this and the Panoramaxx so I bought both. This one has killer head gear with the ability to fine tune the tightness for an excellent tight fit that doesn't squeeze your brains out and give you the killer pressure headache with other ratcheting tightening systems. It also has in and out adjustment so you can pull it away from your face to fit a face mask if you need or make it very close for the best visibility. View area is good, but I wish this had the Panoramaxx area. Responsive shade and memory functions so you can easily setup profiles for each welding type you're doing. I also LOVE that it comes with multiple extra lenses in both clear AND yellow. Every other helmet you have to buy them separately so I really appreciated that. Haven't had it flash me and the arc sensors are very fast acting don't have to close your eyes while you strike up an arc. Also comes with a very decent helmet bag, not a crappy ones that tear if you look at it wrong. I actually use it.
All in all, this is a 100% buy for pros, hobbyist or anyone else who needs a great fitting, well kitted out helmet. I do recommend this over the Panoramaxx for a few main reasons - one, better adjustability. The ratchet system on the Pano isn't fine enough and it's always too loose or too tight. My head is between the adjustment. This one let's you fine tune it for the perfect firm grip and distance from your face. And it's comfy! Second, this comes with extra lenses both inside and outside. Everyone else makes you buy them separately and this you're getting 4 extra with the box! Both yellow and clear. Third, this has a detent that keeps the lid up when you're not using so you're not constantly having to pull it back up while not welding. It stays up great and a firm flick of the head is enough to overcome the detent and cover up. Last, the sensors are great. They don't turn on when you look at a light nor does it flicker. The color is great and the shade works like a champ.

Definitely buy this guy. You'll be mega happy you did.

This is an excellent hood. If you're on the fence, you should get it. The picture is insanely clear. It's like those HD lenses that sharpen everything lol you can see every little thing happening in your weld!

Really only downside is that the replacement lenses are a bit pricey but you get 2 clear and 2 yellow so I'll cross that bridge when I get there. Also, it's super lightweight and sturdy. The touch screen is also really nice, very responsive like a phone.

I weld for a fabrication shop and I'm beyond happy with this hood. I've let my friends weld with it and everyone loves it.

I've welded with plenty Lincoln hoods and yeah they're nice but you're getting better technology and for a better price. Quality is undeniable. It doesn't feel cheap in any aspect.
