Quick Fire Reviews: The MCR 303


Despite having been vaping since 2013, there are some atties that I missed out on, or that I just want to revisit. These are quick reviews intended to touch on something that’s not the newest, not the shiniest, and likely has already had too much said on it. It’s always worth comparing these things to our modern atomizers and see what’s held up and what hasn’t!

I don’t believe I’ll put up any of my own pictures for these, just in the interest of getting the reviews done as quickly as possible.

Disclosure: I purchased this from a friend of mine a few states away for well under RRP, but even at their bananas sales price of about $40 this atomizer is screaming cheap.



  • Price: $40.00 for the multi month long Flash Sale that has been going on (130.00GBP regular price)
  • Height: 30.7mm
  • Diameter: 20mm
  • Volume: 1.8mL
  • Tank Material: PMMA or Stainless Steel
  • Airflow: 1mm, 1.5mm, or 2.0mm fixed depending on your choice (additional caps can be purchased)

Where the Sat22 was thoughtful, so too is the MCR 303 in different ways. The volume may be a deal breaker for some, but filling is so quick and easy that I didn’t find it to be much of an issue. This review was conducted with the 1mm top cap!


The MCR has a dedicated fill port (where you would just use the unused wick hole on the Sat), but you can either leave the port plugged or unplugged with a metal rod in the MCR. The rod gets threaded into the top cap of the MCR, and serves as a guide to get the top cap on in such a way that you don’t jank up your build due to the reduced build chamber in the cap being able to squash your wick and coil.

The flavor is lovely on this atomizer, though. It’s right there with the Sat22, but there is one important difference between the MCR and the Sat22: the MCR 303 can whistle.

I thought it wouldn’t be a problem – I’ve had some noisy atomizers before, but after using the Sat22 for a few weeks before getting into the MCR 303 the noise was driving me crazy. The flavor is bananas! It’s easy to live with! I can build it in a jiffy, fill in half a jiff, but the sound every time I used it was nooooo bueno. The diameter of the drip tip against the airflow was also introducing a little dysphoria (wide bore, tight airflow).

The 20mm diameter may also make people feel a bit odd, as well. I think it looks great on 22mm mods – I really didn’t think it looked bad on my DEV2+.

For those two issues that some may or may not have with the atomizer, there is one thing to keep in mind: this is a $40.00 Genesis style atomizer and it performs wonderfully. It is flavorful, warm, and I didn’t get a single dry hit. If you’re looking for something cheap to try for Gennies, absolutely check these out because who knows how long the prices will remain so low.
