The Boutiq Switch V4 in NYC Sour x Lemon Head puts two citrus profiles on one 2g dual tank body, and that pairing deserves explaining because the two halves are not interchangeable. Both names read as bright on the label. They do not behave the same way once the device is in your hand, and the mechanical selector is what lets you choose between them without the two chambers ever meeting.
What follows is what this particular combination is like to own, what our attribute panel actually records about it, and what the listing costs at the time of writing.
Two citrus routes that do not overlap
NYC Sour is the more aggressive name of the two. Sour cuts in this family tend to arrive with a rind edge and a slight bitterness behind the sweetness, and that bitterness is the part that stops a citrus flavour reading as candy. Lemon Head goes the other way. It is narrower and more confectionery, closer to a lemon drop sweet than to the fruit, with the sugar sitting in front rather than behind.
The practical consequence is that these two tanks do not blur into one citrus experience. If you have ever bought a fruit pairing and found both halves tasting broadly the same by day three, the culprit is usually two flavours built from the same sweet base. Here the sourness of one and the sugar of the other are pulling in opposite directions, which is exactly what keeps a dual tank device interesting past the first week.
Worth saying plainly: our attribute panel lists this device as Version V4, dual tank, 2g capacity, Liquid Live Diamonds extract and USB-C rechargeable. It does not attach an indica, sativa or hybrid label to either half of this pairing. We would rather record nothing than invent a lean, so treat the flavour notes above as flavour notes and nothing more. If you want a lean stated, ask us before you order and we will tell you whether we have it.
Where the selector earns its keep on a citrus device
The V4 uses a mechanical selector rather than a software one. Each chamber is sealed on its own, and moving the switch physically opens the path to one side of the device. Nothing mixes, and nothing carries over.
On a citrus pairing that matters more than it would on, say, two dessert flavours. Sour notes are the first thing to get muddied when two liquids share a path, because the sharpness is a thin top layer rather than a thick base. A device that let even a trace of a sweet reservoir bleed into a sour one would flatten the sour half within days. Sealed chambers are the reason NYC Sour still tastes sour when you come back to it after a fortnight on the other side.
It also means you can genuinely park one tank. Plenty of buyers run Lemon Head as the everyday side and keep NYC Sour for the times they want something with more bite. That only works if the parked tank is still recognisable when you return to it.
Reading the price on this listing
At the time of writing this page shows $25.00, marked down from a $30.00 list price. That is the price for one sealed unit with both chambers filled, not per tank and not per gram. Sale pricing changes, so the figure on the product page at checkout is the one that counts, not the number typed into a description.
What you receive is one boxed device with a batch code printed on the packaging. Dispatch timing and packing method are things to confirm with us at the point of ordering rather than assume from a description page, because they depend on where the order is going and what is in stock that week.
Mistakes people make with a sour pairing
The most common one is chasing the sour note by pulling harder and longer. Sourness sits on the front of the draw, and a long pull does not intensify it, it simply pushes more of the sweeter body through afterwards and buries the part you were trying to reach. Shorter draws with a real pause between them keep NYC Sour reading as sour.
The second is judging a device straight out of a cold delivery. Concentrate that has been sitting in a cold van is thicker than it should be and the first few draws will read muted on both sides. Let the unit reach room temperature indoors before you form an opinion about either tank.
The third is heat. Leaving any 2g device on a dashboard or a sunny windowsill is the fastest way to lose the delicate part of a citrus profile, and the delicate part is most of what you paid for here. For general context on cannabis and what is and is not established about it, the NIDA cannabis research overview is a reasonable neutral starting point.
NYC Sour x Lemon Head, buyer questions
Which of the two tanks do people finish first?
In our experience Lemon Head goes first, because it is the easier of the two to reach for without thinking. NYC Sour tends to get used deliberately. That is not a rule and buyers who came looking for a sour cut in the first place usually reverse it.
Is this a good first V4 to buy?
It is a reasonable one, yes, because the two halves are far enough apart that you learn what the switch is actually for. A pairing of two similar flavours teaches you less about whether the format suits you.
Do you list an indica or sativa lean for this device?
No. Our attribute panel for this listing carries version, tank count, capacity, extract type and charging, and no lean. We are not going to guess one in a product description.
Can I use both tanks in the same session?
You can, and the selector is designed for exactly that. Be aware that going from Lemon Head to NYC Sour reads clearly, while going the other way can make Lemon Head seem flat for a minute or two because your palate is still on the sour side.
How should I store it between uses?
Upright, indoors, away from direct sun and away from anything that gets hot. Upright matters on a dual tank device because it keeps both chambers settled over their own intakes rather than pooling to one side.
Adults 21 and over only. Confirm the batch code on your box before your first draw, and check current dispatch times with us rather than assuming them.
