4 FLAVORSSide by side
Muha Meds THCA Cartridge 2g vs Melted Diamonds Gen 3
These are the two Muha Meds products that most often get compared, and they are not the same kind of thing at all. One is a cartridge that arrives incomplete on purpose; the other is a finished device. The decision turns almost entirely on whether you already own a 510 battery — and if you do, the maths changes completely.

Specs, side by side
Every figure below is the one published on each product page. A highlighted cell is the side with the clearer advantage on that row.

The capacity gap is bigger than it looks
3500mg is 3.5 grams, against the cartridge's 2 grams — 75% more extract. The Gen 3 costs more outright, but it does not cost 75% more, so on price per gram it is the better rate of the two. The table above carries the live figures.
That inverts the obvious reading of the price tags, and it is the single most useful fact in this comparison. The cartridge is not the budget option; it is the smaller option.
Except the cartridge isn't a complete purchase
The cartridge needs a 510 battery and does not include one. Our two are the Ooze Twist Slim Pen 2.0 and the EF420 Vertex, and either one roughly doubles what a first-time cartridge buyer actually spends.
Bought that way the Gen 3 comes out ahead: cheaper all in, and holding more. The cartridge only wins on the second purchase, when the battery is already yours and a cartridge is the whole cost. If you expect to buy repeatedly that crossover arrives immediately and keeps paying; if this is a one-off, it never arrives at all.
Control: built in, or bought once
The Gen 3 publishes three voltage settings plus a preheat option. That is a real specification and it is built into a device you will eventually throw away.
With a cartridge, control is a property of the battery instead. The EF420 Vertex lists adjustable voltage and a preheat setting; the Ooze Twist Slim has a Flex Temp variable voltage dial. So the cartridge route buys that capability once and keeps it across every cartridge afterwards, while the Gen 3 buys it again with each device.
What neither of them publishes
Muha Meds does not publish a coil type, a battery capacity in mAh, or a charging specification for the Gen 3, and our product data carries none of them. Nor is there a THCA percentage or a lab report number for either product. We do not print figures we do not hold, so those rows are absent rather than filled in.
Both products label strains as Sativa, Hybrid or Indica the way the manufacturer classifies them, and that is a statement about the label rather than about anything else.
The verdict
Which one, for who
You already own a 510 battery
Muha Meds THCA Cartridge 2gThe cheaper of the two with nothing else to buy, and the battery you already own supplies the voltage control the Gen 3 builds in.
You own no hardware and want one purchase
Muha Meds Melted Diamonds THC-A Gen 3 Device 3500mgOne purchase and it is complete, against a cartridge plus a battery — and it holds 3.5g against 2g.
You buy regularly and want the lowest running cost
Muha Meds THCA Cartridge 2gA battery is a one-time cost. After it, every cartridge is cheaper than a new Gen 3.
You want the most extract in one object
Muha Meds Melted Diamonds THC-A Gen 3 Device 3500mg3500mg against 2000mg, and the better price per gram of the two.
Common questions
Does the Muha Meds cartridge include a battery?
No. It is a 510 cartridge only; a 510 battery is required and sold separately. The Gen 3 has its battery built in.
Which is cheaper per gram?
The Gen 3. It holds 3500mg against the cartridge's 2 grams — 75% more extract for considerably less than 75% more money.
What voltage settings does the Gen 3 have?
Three, plus a preheat option. With the cartridge, voltage control comes from whichever 510 battery you pair it with.
Can I use the cartridge with any 510 battery?
The 510 thread is standardised, so it connects to any of them. How well a given battery drives it is a voltage question.
