I ordered and received a solar filter, from TEMU. To my pleasure, it is a well constructed 58mm screw in filter. 58mm for $13 free shipping. 82mm is $17. Cost is much lower than other sources, " Haida - Solar Filter $77–$138"

The TEMU filter outer side is a mirror like surface, the base is glass not plastic film. The search description:

BE CAUTIOUS!

From the TEMU site; no certification as safe, statement not to use for eye viewing and may cause CMOS failure

Solar film laboratory ISO12312-2 certification through the United States；
Warning: in use process, it is forbidden to remove the solar film, play directly into the sun causes CMOS camera is focused on the overheating burn out, so the human eye observation will hurt the human eye.

In the description it state, "No Certification" contrary to the ISO statement above.

BE CAREFUL!

After checking the ISO website, TEMU is not an authorized ISO vendor. Saying they are is not the same. Especially when their note is "through the United States." ISO testing is through independent labs who are authorized to use the ISO logo. Note TMEU doesn't use the logo or a specific lab in their web description.
As I said, be careful.
You only have two eyes.
Note too, that TEMU is noted for very low prices on products of questionable quality.

With ISO we digress. Much negatives about TEMU on the net, as with TESLA... Typical one death with TESLA is more than the 1000 with out the driving system! Poor mouthing is more interesting to the population than praise and facts. Is the TEMU filter a good choice is the focus of this post... my bet is that it is... I will test it tomorrow, if the sun shines thru the clouds.
ISO certifies products and is also a ISO improvement scheme for companies to follow.
BUT
You are correct that TEMU is not an ISO certified vendor... to quote:
ISO 9001 is a standard for quality management systems and does not maintain a list of approved vendors.

https://www.iso-certification.us/iso-9001-certification/documents-records/list-of-approved-vendors.html

Instead, ISO provides guidelines for organizations to establish their own supplier selection and evaluation processes based on their specific needs and requirements. Their are consultants to help.

I was tech manage and we qualified our adhering to ISO standards. [Oh, ouch 30 y ago~!]
Retailers can be certified... but not required... ISO flags as are others wave proudly under the USA flag.

Thank you www80a for bringing up the subject, I will be reading the "Walmart Case Study"

In the past, many people used welder's glass for observing the eclipse. Were these ISO certified?

MrPhotog

Since my cameras are mirrorless, I would worry much more about any sensor damage than eye damage. Since I’m going to be looking at an electronic monitor, it is not the same as looking through an SLR. The image on an electronic viewfinder ( or rear screen in live view on a DSLR) isn’t going to be any worse than using it for any of the other things I shoot. Even if the sensor receives a high dose of UV, that doesn’t get sent to the EVF for me to see.

The problem is only with optical viewfinders where the filter is all the protection that stands between the light and your eye.

Why is Temu being compared to Ali Baba. Both are questionable websites selling low end junk.

And some people held a glass slide over a candle and used the smoked glass to view the sun. (me included-late 1950's)

I'm sure that wasn't anything certified.

I recently purchased a battery operated coffee mill grinder from Temu. I am very pleased with the low price and high quality. Price was about the same as my hand operated coffee mill grinder that I bought from Amazon. Guess what - both made in china!

Ollieboy

That still doesn't change the fact that Temu sells low quality products.

Yes, negative is easy to talk about. There was a study by an astronomer PhD comparing polarizing [?] Filters based on price vs quality... it was through and scientific... based on ratings... sorry I do not have the reference. Price and quality were only semi correlated some low cost good quality some expensive lower than the data regression line. Hi price in the minds of many is erroneously hand in hand, equated, with quality; thus TEMU filters must be bad, unclean as in the old human cast system.

Float glass has improved to the point that it is as good as optic ground glass for filters. Again from memory and reference search is time consuming and not the subject of this post. AS with many thing can the human eye detect the difference in photo quality... often differences are doubtful.

Coffee that stevel mentioned is more important in the AM than a camera. Mr Coffee is never mentioned in the espresso tests being a $50 item and not 15 Bar pressure. Add a couple of 51mm paper filters makes a difference tad increase in pressure and flat distribution of the water vs drilling a hole thru the grounds.

I have bought a lot of good not found elsewhere things from TEMU and not useful stuff, was my fault. Return was easy for refund. Size, was a problem with shoes by their sizing my normal 12 is tight... having learned, i just order two 12.5. which should be fine. I ordered a hand strengthen device 2@$8, I requested a return and the reply was "Will refund cost to your account, keep do not return." They pay return just as Amazon does.

At 87 my retirement has not shrunk, but the expenses have swollen, much0 ... cost counts so TEMU and the others are my shopping spots. Any way most stuff is made in China.
