Lost Mary Cosmic Edition Flavors Review

There is no shortage of flavor options for the Lost Mary OS5000 or Lost Mary MO5000. There is even an superpowered, dual-mode Lost Mary MT15000 Turbo. But the classic MO5000 is far from long in the tooth.

But if you are looking for a Lost Mary Smart Vape with a battery life and e-liquid indicators, plus dual mode performance, check out our Lost Mary MT15000 Turbo review. It is a serious piece of kit for adult vapers, and churns out up to 22-watts of power. 

Back to the redoubtable OS5000, it still delivers top-tier flavor, and with a next generation coil can provide pristine notes through every puff. The more efficient design of this coil is said to improve efficiency by up to 50 percent, while still providing dense vapor.

But the real story here are the Cosmic Edition Flavors. There wouldn’t seem to be much room for new options when the Lost Mary line-up is swamped with options, so let us see how these three new Lost Mary flavors stack up.

Bright Red Lost Mary OS5000 Cosmic Edition

The mysteriously named Bright Red Lost Mary OS5000 was inspired by a bright red tropical fruit punch. Specifically, one that once used a very pugilistic character in a very strange hat for a mascot. While this flavor will not punch you in the mouth unprovoked, it does pop with flavor. This is a solid fruit punch vape, with an danger of overwhelming sweetness curtailed with tart fruit flavors. A true beverage vape, Bright Red is one of the better berry medley and tropical inspired disposable vape flavors on the market today.

Berry Cherry Lost Mary OS5000 Cosmic Edition

A cosmic swirl of tart and sweet cherry has been added into a classic berry medley blend. Fans of mixed berry vapes will not find the cherry notes overwhelming. Conversely, the newly popular flavor of cherry is well-represented in this sweet and mildly tart flavor.  

Sour Berry BG Lost Mary OS5000 Cosmic Edition

BG is an acronym for a chewable confection that you do not want to get stuck to the bottom of your shoe. With that in mind, it is easy to envision what the Sour Berry BG Lost Mary OS5000 Cosmic Edition tastes like. There are sour confection notes layered atop a sweet berry base. The balance of flavors pretty closely resembles BG, making this a very nostalgic option as well. Fans of sour and sweet confection flavors will not want to miss this one.

Blueberry Watermelon Lost Mary OS5000 Cosmic Edition

Blueberry and watermelon are usually the centerpiece flavor in an iced vape, at least in the world of nic salts and disposables. In the case of the Lost Mary Cosmic Edition, they are combined into a great and cohesive flavor. The sweet and airy nature of the watermelon flavor makes this taste almost like a refreshing beverage. The blueberry notes are very distinct. While you may not mistake this for real cold-pressed fresh fruit juice, it is extremely balanced and impressively authentic. The result is a top-tier fruit fusion with a hint of coolness.

Watermelon Kiwi Lemonade Lost Mary OS5000 Cosmic Edition

Another flavor with a heavy blast of watermelon, the Watermelon Kiwi Lemonade Lost Mary OS5000 Cosmic Edition is adds a bit of tart kiwi to an excellent watermelon and lemonade vape. Lemonade rarely gets a chance to be enjoyed by itself, perhaps it is too caustic for the average vaper, but it plays a big role here with the refreshing sweetness of watermelon melding with the tart notes.  

Banana Split Lost Mary OS5000 Cosmic Edition

It is a great news for adult vapers that more dessert flavors are appearing in disposable vapes. Lost Mary has not been late adopter per se but they definitely needed the Banana Split Lost Mary OS5000 Cosmic Edition to flesh out the lineup. The banana flavor is creamy, as are the additional cream notes and the blast of coolness. This ends up being a superb banana ice vape, with plenty of Gros Michel banana flavors and even more smoothness than the typical rival.

Our Verdict

The next generation coil adds a fresh coat of paint to the time-tested hardware and the new flavors are outstanding. Whether it is enough to deter Lost Mary fans from scoping out the longer-lasting MT15000 Turbo remains to be seen. While it may not have all the smart features, for a solid vape with dense flavor and a nice draw, it is tough to beat the OS5000.

None of the flavors are too far outside the box. A lot of fruit and menthol fusions here, but Banana Split is a nice change of pace. Between the Raz TN9000, the American-made Fifty Bar Disposable and flavor like this banana split inspired masterpiece, adult vapers looking for a break from cookie-cutter tropical fruit+menthol flavors finally are getting some great options in the disposable vape world. Bright Red is another luminary, tasting unironically like a fruit beverage straight from a blue 1980s can.
