Three names straight out of the sweets aisle
Grape Ape, Jelly Roll and Rainbow Belts is a confectionery lineup and it makes no attempt to hide it. Two of those three names are literally sweets, and the third is one of the older purple cuts still in circulation. All three lean indica. Nobody is buying this device to get through a morning.
What is worth noticing is the age gap between the cuts. Grape Ape has been around long enough to be a reference point, while Jelly Roll and Rainbow Belts belong to the current wave of candy named selections. Putting an established purple next to two modern sweets is a deliberate contrast, and it is the most interesting thing about how this trio was assembled.
There is a broader point buried in that. Candy naming has become a shorthand for a certain kind of flavour engineering, and it works commercially because those profiles are immediately likeable. What it does not do is last, and a device made entirely of them tends to lose its appeal before the oil runs out. Including one older cut is how you avoid that, and it is why this trio holds up better in week three than the pure sweets configurations do.
Grape Ape, the oldest cut on the device
Grape Ape tastes the way people remember purple cuts tasting before candy terpene profiles took over. Deep grape, yes, but with a woody, slightly musky undertone that the modern sweets never have. It is less sweet than either of the other two positions and considerably more grounded.
That makes it the tank that ages best across the life of the device. Candy profiles are bright and fragile. Grape Ape has structure underneath the fruit, so it is still recognisably itself in the last quarter of the tank, which is more than can be said for a lot of sweeter cuts.
If you are choosing this listing over the other purple configurations in the range, this is the position that justifies it.
Jelly Roll and Rainbow Belts, the two modern sweets
Jelly Roll is soft, sweet and pastry adjacent. There is a jammy centre to the flavour and a doughy roundness around it, and the whole thing reads as dessert rather than as fruit. It is the mildest of the three on the palate and the one that suits being used repeatedly without becoming tiring.
Rainbow Belts is the loudest. Sour sugar over mixed fruit, exactly like the sweet it borrows its name from, with a brief tartness on the inhale that gives way to straightforward sweetness on the exhale. It is the tank that gets used when the device is shared, because it is instantly recognisable and asks nothing of the person using it.
The two are close enough that using them back to back blurs them. Alternate either with Grape Ape and both stay distinct, which is the practical argument for having an older, less sweet cut on a candy device at all.
A word on how people actually use this one. In practice most buyers settle into a pattern of two tanks rather than three, with Grape Ape and one of the sweets in rotation and the other sweet used occasionally. That is not a criticism of the third position. It is simply what happens when two cuts sit close together, and it means the device lasts longer than the arithmetic suggests.
Price, specification and the practical bits
What you are buying is a single V5 unit: three sealed tanks, a mechanical selector between them, 2g stated as the capacity, liquid live diamonds as the extract and USB-C charging. It is not refillable and the three strains are fixed when the device is built.
At the time this description was written the page showed 30 dollars against a 35 dollar list price. That is the complete device rather than a multipack. Store pricing changes and the listing itself is the only figure to rely on.
On care, sweet cuts are the ones that suffer most from heat, and two thirds of this device is sweet. Warmth thins the oil, flattens the sour edge on Rainbow Belts and turns Jelly Roll into an indistinct sugar note. Keep it upright, keep it at room temperature and keep it out of the sun, and use an ordinary USB-C cable rather than a high output supply.
For a factual counterweight to product marketing, including this page, the National Institute on Drug Abuse cannabis research overview is a short and useful read.
Questions about the Grape Ape, Jelly Roll and Rainbow Belts device
Are Jelly Roll and Rainbow Belts too similar to justify separate tanks? Used back to back, they overlap. Used either side of Grape Ape, they do not. The sequencing does the work.
Is Grape Ape the strongest tasting of the three? Not the sweetest, but the most structured. It is the flavour you would still identify blind.
Does this trio work for daytime use? Not really. All three lean indica and the sweetness compounds. A mixed configuration is the better buy if you need coverage across a day.
Why has the sour edge gone from Rainbow Belts? Heat, in almost every case. Sour top notes are the first casualty of a device stored somewhere warm.
Which position should a new buyer try first? Grape Ape. It gives you the clearest read on the hardware before the sweeter tanks coat the palate.
Is 30 dollars the ongoing price? It was the sale price on the day this was written. The product page decides.
