I have had it for almost 3 years without changing batteries and without any issues.
The shading adjustment has a small difference in terms of the scale you choose, but I think it is unnecessary.
Although, let's face it, we are dealing with eyes that are worth every penny, there is no need to spend more because you can do your job and not have to spend extra

Very good for its price, the truth is that I have never used an electronic mask before and I cannot give an opinion. It is the first one I use and it is very good!!!!!

For amateur use, it is very good. It is the first time I use a mask and it solved my hands. I hope in the future it will not disappoint me, although "a good day is evident from the morning."

Very good for its price, it requires a little experimentation and getting used to, but otherwise it's fine. A bit heavier than I expected, but easy to get used to.

Just received it. Very good, the only downside is that it needed a larger 1-2 centimeters field of view.

Satisfied with its operation, although I did not understand the shading levels. Easy delivery. Cheap material for the glass, almost nonexistent instructions but on the other hand, simple to use. Good fit on the head and overall I highly recommend it regardless of the brand, buy an automatic mask, you will be saved. No comparison to the old masks... I'm talking about amateurs, professionals know. I was saved anyway and I stick better by 50% just by seeing where I stick

While I initially gave it one star, I am reconsidering my opinion and giving it 3 stars. The problems I identified are 2 and they are as follows: when working on a 90cm bench with 1m below, the lower part of the mask rests on your chest and you don't have a good field of vision. If you work on your knees, it doesn't bother you. Secondly, the mask opens slowly after welding, resulting in a lot of wasted time. It is possible that mine has a problem. So, it's okay.

I bought the mask following the good reviews and found that a) when I removed the protective plastic, the outer glass was very scratched and b) the shading intensity adjustment does not work, it only gives the maximum.

A great simple and affordable mask. It is my first one and it solved my problem. Convenient and easy to adjust. It comes with 2 extra filters and built-in batteries. I highly recommend it.

Very good mask. It works with both sunlight and batteries, has shading settings corresponding to glass 9-13, and very fast shading.
For its price, it is the best you can get.

Lightweight. Large field of view, instant response, and the best thing of all that you can only find in masks with quadruple the money is that besides the photocell it has a built-in battery with an indicator when its level drops.... a one-way street for its money

Lightweight mask doesn't tire. It is very good for amateur use. Very good response activation. Solar cell and battery!

Guys, this mask is everything. Especially for beginners, you can do some super cool tricks. I regret not getting it earlier!!!

Kids, it is lightweight with a large field of vision. Excellent shading and protection. I stick for hours without any problem. I highly recommend it without hesitation!

I don't have a point of comparison, but from the work I did, I saw that it is a good mask and it does its job just fine. I recommend it!

I bought the TOTAL TSP9306 about 1.5 months ago and I am extremely satisfied. Lightweight, fully adjustable headband and with foam material on the front part that touches the forehead to avoid discomfort. Its electronics work flawlessly and the shading happens instantly. As for its advantages, it has multiple shading level adjustments (9-13 din), dual power supply with solar cell and lithium battery, high UV/IR protection (din 16), large field of vision, spare lenses for the cassette included in the box, and of course its low price. I spend hours welding with it and haven't encountered any issues whatsoever. I don't see anything that it should envy from other more expensive ones.
