Not long ago we did an article on a yet to be released Smart Bottle. While that device still hasn’t hit the market, we have encountered something which boasts many of the same features: the Mark One Pryme Vessyl. Designed to be able to sync up with fitness trackers such as Fitbit, Jawbone UP, or Apple Health app, the Pryme Vessyl provides a method to digitally track your water consumption throughout the day without having to do anything but drink from your Pryme Vessyl.
In the article “How My Fitbit Is Chaning The Way I Drink Water” I highlighted how fitness trackers can be used to track water consumption and daily hydration needs. However, in that article I pinpointed the largest issue with the current state of technology being the need to manually input water consumption data as you drink water. A smart bottle bridges the gap between these technologies, allowing you to track your water consumption as you consume it. So is the Pryme Vessyl the missing link? Let’s find out.
(UPDATE: Since this was originally posted, nuun Hydration has launched the Pryme Vessyl 2nd Edition. We got a chance to try out the new model and it solves many of the issues we pointed out below, like the connectivity problem, and improves the “Pryme” calculations. Please note that this article is concerned with the Mark One original edition of the Pryme Vessyl and not the new 2nd edition. For a brief summary of our thoughts on the 2nd edition, check out our Best Hydration Tracking Smart Bottles article.)
A First-Generation Smart Bottle You Can Own Right Now: The Mark One Pryme Vessyl
First of all, we think it is important to note that the Pryme Vessyl definitely represents a technology in its infancy. That said, the Pryme Vessyl has managed to do pretty well for itself – on some fronts. The key feature of the Pryme Vessyl is its ability to track the amount of water you drink throughout the day, syncing up via BlueTooth to your iOS device or to a compatible fitness tracker.
The tracker seems to keep accurate tabs on how much water is being consumed through the Pryme Vessyl. All you have to do is fill it up, and so long as it is properly connected to your device, it will track consumption as you drink. It gives you a fairly reliable measurement without having to input any data yourself. This is, more or less, what we’ve been looking for. But sadly, there are a few kinks yet to be worked out.
Finding Your “Pryme”
On the front of the bottle is a line which fills up with light depending on how close you are to your “Pryme.” If you’re at your “Pryme,” the blue light at the top is illuminated, and you are, by the Pryme Vessyl’s calculations, properly hydrated. This is where things get a bit wonky.
Rather than being based on any fixed number or amount of water to drink, the smart bottle calculates your “Pryme” based on your height, age, sex, weight, and sleep cycle. It asks for this information the first time you start up the app, or it can be synced to your fitness tracker to automatically get this data. If synced with a fitness tracker, the Pryme Vessyl also takes your activity into account in determining your optimal hydration level.
Unfortunately, we’ve come to conclude that Mark One should probably check their numbers on this one. Despite a bunch of research linked on their website, I seriously question their ability to calculate optimal hydration levels.
The optimal hydration level on our Pryme Vessyl seemed to vary wildly even though my activity level and day to day habits didn’t really vary. Probably the most telling sign of there being something amiss with the way my “Pryme” was being calculated was the fact that it really clashed with my natural instincts for water drinking. Despite trying to match my “Pryme”, it routinely fills up before I feel like I’ve quenched my thirst, or sometimes eggs me on to drinking much more water than I feel like I should.
The fact that their algorithm for the “Pryme” was a little weird was disappointing, definitely. But given the Pryme Vessyl’s ability to sync up to my Fitbit and give me an accurate measurement of my water consumption, it wasn’t a complete deal breaker. Unfortunately, the connectivity problems would definitely be enough for some people to put down their Pryme Vessyl.
I don’t have it as bad as some others report. The Pryme Vessyl sometimes has difficulty connecting to my iPhone app, but tends to connect fairly reliably to my Fitbit Charge HR. On a few occasions, it has completely failed to sync, forcing me to reset the bottle. Other users have reported having this issue far worse, with poor connectivity making the Pryme Vessyl almost useless. Hopefully this is a limited issue which the manufacturer can get worked out.
The Pryme Vessyl isn’t all bad, it does have some pretty neat features. The bottle itself looks pretty cool, featuring a durable white Tritan plastic exterior. Inside, the container itself is all glass, which is regarded as one of the best storage materials for drinking liquids, although it does make the Pryme Vessyl a bit more fragile than it could be otherwise.
Probably one of the coolest features the Pryme Vessyl brings is the wireless coaster charger. All you have to do to charge the bottle is set is on the neat, modern looking coaster, and without having to fiddle with any wires the device is charging. Also pretty nifty is the “Pryme” meter on the front of the bottle lights up when you tilt the Pryme Vessyl away from you.
The lid on the bottle is also quite well designed, featuring a smooth magnetic cap that slides open and locks securely into place providing a more than adequate leak-proof seal. Aesthetically, we can’t fault the Pryme Vessyl’s designers: the bottle is sleek, futuristic looking, and quite practical.
Unfortunately, the Pryme Vessyl has glaring flaws. It does earn some points from the fact that it is, in many ways, the first of its kind. With other smart bottles posed to take to the market in the years ahead, we are likely to see a lot of things like the Pryme Vessyl, probably becoming cheap and widely available. At the early outset, the Pryme is providing a pretty cool product, and for anyone interested in easily tracking their water consumption, it is a decent investment.
However the technological flaws with connectivity issues and the more or less failure of their “Pryme” calculations makes the Pryme Vessyl a miss on many fronts. Although it looks cool, and manages to track your water consumption pretty accurately, it would really benefit from the ability to turn off the “Pryme” and set your own goals, or to just track your water intake, not aiming to provide you advice as well.
At the end of the day, it is something of a novelty. With a pricetag hovering around $99, it is definitely not cheap, but for anyone willing to take the risks of diving into the first generation of smart bottles, potentially an interesting product.
Due to some of the glaring technical issues, as much as we want to like the Pryme Vessyl, we have to give it a sub-par 3/5 star rating.

Big Dreams From Mark One
The Pryme Vessyl is actually a spin-off of a much more ambitious project underway from Mark One. Where the Pryme Vessyl tracks nothing more than the volume of the liquid (assumed to be water) within it in order to give consumption metrics, the Mark One Vessyl seeks to solve the incredibly tricky challenge of knowing what its contents are. Designed with the aim of giving users a sort of real time readout of the nutritional facts of whatever is poured into the Vessyl, the project could eventually provide the market with a pretty incredible tool.
Sadly, the Vessyl has so far been beset by technical challenges and delays, overshooting its hopes of reaching retailers in 2015 and still without a firm release date as of this writing in April 2016. Aiming to track everything from calories to caffeine content, it is easy to see how the Vessyl could be delayed for quite awhile, leading some to speculate the company many have promised too much from the product.
Here is a brief clip from Forbes which takes a look at the Vessyl.
