I consider the upcoming MIRA C21 review to be the review of the year 🎬
Not because the mask is any good for the asking price 😏 but because we’ll finally set the record straight on the numerous issues this mask has.

The so-called “reviews” from MIRA shills I had to sit through didn’t mention a single one of them. How convenient! 🙃

Now, the resemblance between MIRA C21 and the legendary horse mask 🐴 is so uncanny that I had to warn my crew not to mix them up while prepping for filming.

Despite my best efforts, both masks ended up on set anyway.

Stay tuned — this one’s going to be fun. 🔥

🚨 We’re in turbo production mode this month! ⚙️💨
Our upcoming MIRA C21 gas mask review is almost ready and oh boy, we’re having way too much fun with this one. 😅

Truth be told, that’s only because we didn’t have to pay $470 for this undercooked abomination, otherwise I’d be furious. 💸🤦‍♂️

For a mask this expensive, there are so many mind-boggling design choices that are simply inexcusable and we’ll be tearing into all of them in the full review. 🔍🔥

Originally, we planned to compare C21 with Avon C50, but after really getting to know this thing, we decided that it would be better to compare it to GuZu OM-2020 a.k.a MIRA CM-8M to show just how bad C21 really is. 😬☢️

Step back in time with us as we explore a rare Czechoslovak radiation detector from the 1960s! Měřič záření alfa, beta, gama measures alpha, beta, and gamma radiation - all from a massive suitcase-sized kit. Join us as we unpack its components, explore its vintage technology.

🎥 To catch up after our holiday break, we’ll be sharing more videos than usual this month.

Modern radiation detectors are usually compact — sometimes even pocket-sized. 📏🔋 But more than 60 years ago, carrying a radiation meter was basically a workout. 💪📻

In this episode, we’ll take a closer look at a fascinating and rather rare Czechoslovak device: Měřič záření alfa, beta, gama – which translates to Alpha, Beta, Gamma Radiation Meter. 🇨🇿☢️

Don’t miss this deep dive into Cold War-era tech! 🕵️‍♂️📼

Coming soon: our full review of the MIRA C21 gas mask. It costs almost $500 but is it worth it? Spoiler: we don’t think so. Stay tuned for the breakdown!

A Huge Thanks to Our Supporter! 🎉

We’d like to give a big shout-out to our amazing supporter for providing us with a CBRN respirator I’ve always been eager to get my hands on - Scott GSReS.

This marks a major milestone for us as the long-postponed review (over a year in the making!) is finally nearing completion. The final piece of the puzzle was getting hold of a GSReS, and now that it’s here, we can move forward with creating the ultimate head-to-head comparison between all three variants — FRR, GSR, and GSReS.

This will be our most detailed and comprehensive CBRN respirator review yet, so stay tuned! 🥽⚡

💬 Have you used any of these masks before whether it's FRR, GSR, or GSReS?

I was so relieved after releasing our GP-7 review, thinking I’d never have to bother with that mask again… and here we go again 😬

Even though I said that we won’t be reviewing other GP-7 variants, most likely ever, one GP-7V found its way to us without paying ungodly money for it on eBay. 💸

We already made pretty clear how badly GP-7 sucks 🤦‍♂️… but thanks to the comments from many of you, we realized this whole line of masks came out of the factory in “various qualities”. That’s pretty unusual (and shocking) since we’re used to consistent respirator quality. Soviets, what I say. 🤷‍♂️🔨.

That’s why I’m actually eager to compare GP-7V with GP-7 and its flaws🤞. Plus, this will be the first time we’re testing a drinking system on a Soviet mask. 🥤😲
Just note: this won’t be a full-on review (don’t worry, we’re not wrecking our tight release schedule 📅). It’ll be more of a fun update video.

So… excited? 🚀😎

🔥 C21 Gas Mask First Impressions 🔥

After a few days of testing C21 and digging through the painfully limited info available, I can honestly say two things:
😵 This mask is mid at best…
💸 …and it’s absolutely not worth €/$500.

To be blunt, in light of what we now know, it feels downright insulting.

👉 Many people don’t even realize C21 is just a stripped-down version of M21 gas mask. Thankfully, we now have a much clearer picture of what’s really going on.

Here’s the kicker:
MIRA Safety markets C21 with the following description: “Patented Side Connector: Easily swap filter mount between left or right without tools.”

⚠️ That’s misleading. C21 only comes in a single-port version (left or right), with no swap option. The swappable connectors exist only on M21, the Italian Army’s regulated version, which also features an Auto-Shutoff Valve for safe filter changes.

This is the result of copying product information from a poorly structured DPI catalog without proper review. For a company reselling protective equipment, providing accurate and reliable specifications should be the minimum standard.

Given what we already know about MIRA Safety and their business practices, it’s hard to say whether this is another instance of their incompetence - or deliberate misrepresentation of C21 features.

This isn’t just a matter of having a single filter port, like it was the case with the Avon FM12 we reviewed. The entire M21 design (with its questionable placement of the exhalation assembly and that massive front profile) was built around removable connectors. Without them, C21 ends up bulky and overbuilt for no reason.

⁉️ So what does C21 give you?

👉 No swappable connectors
👉 No shutoff valve
👉 An insulting €/$500 price tag
👉 And much more (To be continued)

We’ve got a lot more to unpack in our full review next month, so stay tuned 👀

⚠️ In our latest gas mask review, we've broken down features and accessories of Skyddmask 90 from SES Protection, and tested how it performs during strenuous physical activity. ⚠️

We evaluated the mask’s compatibility with a low-cut ballistic helmet, along with its impact on sight alignment and rifle handling.

We also tested Skyddmask 90 with Sweden’s most infamous weapon of mass olfaction - . Do you think Skyddsmask 90 could survive the apocalyptic horror of fermented herring juice vaporizing in real time? Watch the video to find out!
