MAD DOG V2 Collaboration Edition Atomizer Review

 　 This review is for the Mad Dog V2 Collaboration Edition Atomizer, also known as the Crazy Dog 2nd Generation with the Suck Suck Fun. The atomizer is nicknamed "Two Dogs" online. In my review articles, as long as there is an image, whether it's a group test, independent review, or something else, I ensure an objective and truthful description of the product, neither exaggerating nor criticizing. I am just a player who won't forget my original intention. If there is no image, you can tell from the text that there may be a tendency to either praise or criticize.

   　 The packaging is black and covers the product well, and the box is not too large.    　 On the other two sides, the golden dot in the upper right corner indicates that the atomizer inside is golden.    　 The lid and bottom of the packaging box have images, and the bottom has information about the contents and anti-counterfeiting labels. Inside, there is one atomizer, eight screws, one screwdriver, two large silicone rings, and one small silicone ring. This should be the atomizer's accessories, but it's not quite right.    　 Opening the box reveals the atomizer and the Suck Suck Fun e-liquid chamber.    　 Lifting the black foam fixing slot and uncovering the black foam base reveals a plastic sealed bag.    　 Inside the plastic sealed bag are two screwdrivers, both hexagonal. The small black one is for the upper screws, and the larger white screwdriver, which is not mentioned, is for the bottom filling screw. There are three silicone rings, and one normal positive screw is not mentioned. There are four replacement hexagonal upper screws and four replacement flat upper screws.    　 No! Look at the packaging box; the number of words is the number of items included.    　 It looks like an RDTA; the top is the atomizer, and the bottom is the oil storage chamber, but they are actually two completely separate parts with no cotton to guide the oil in between. The atomizer has a black drip tip and a golden outer cover, with a golden line embedded near the top and two square air inlets symmetrically opened near the bottom. The very bottom has a heat-insulating pad.    　 The atomizer clearly has the words MAD DOG on it, and below is the self-drawing oil storage chamber of the Suck Suck Fun, which I still prefer to call Suck Suck Fun for convenience.    　 The bottom of the Suck Suck Fun.    　 The logo on the atomizer.    　 When the two parts are disassembled, it is actually a simple structure; the Suck Suck Fun does not have a top cover, which surprised me.    　 The inner view of the top cover shows that the craftsmanship is quite good.    　 The base part has dual posts with four holes and four hexagonal screws. There are two sealing silicone rings to ensure airtightness. You can see the wide air inlets on both sides, with the bottom surface inclined upwards to facilitate airflow directly to the coil. This wire is what I installed; it is not the best just because it was sold to you, nor is it the one that comes with the packaging.    　 The width of the air inlet is not small, and the bottom surface is inclined directly towards the coil.    　 The Suck Suck Fun can be easily disassembled, and you can see the air holes.    　 The Suck Suck Fun does not have a top cover; I don't know why it was designed this way.    　 The air hole is fully open, which minimizes the oil guiding force.    　 The air hole is fully closed, which maximizes the oil guiding force.    　 The atomizer's wire is a four-core Clapton, 4X26ga+40ga, with a 3.0 diameter, 7 coils, dual setup, and a resistance of 0.18 ohms.    　 The cotton used is ordinary Muji.    　 The cotton burning image shows a huge fan shape, which is nice. From this image, you can see that the inclined design of the air inlet plays a role, as the fan shape diffuses according to this angle.    　 After filling the Suck Suck Fun with oil, which is mango smoothie 888, the PG/VG ratio should be 50:50. The air inlet of the Suck Suck Fun is the smallest, which is also the fastest for filling. After taking ten puffs, I removed the atomizer cover, and it showed signs of being low on oil.    　 It is actually simple to guide oil; just close the atomizer's air inlet, take a puff, and oil will come in. However, the strength of that puff is very difficult to control; if it's too small, you won't get any oil, and if it's too big, you'll suck up half a tank of oil. At this point, if you open the atomizer's air inlet, some oil will definitely leak out; if you don't open the air inlet, you can't play, so be ready with some paper towels.    　 After installing the wire, I screwed it onto the main device, but it showed that it couldn't find the atomizer! I had to disassemble the atomizer and loosen the positive screw a bit to recognize it. The Suck Suck Fun has this issue; it often can't find the atomizer.    　 1. The wire holes are very large, making it easy to install the wire.    　 2. The drip tip's anti-condensation design is excellent; please note that there is a groove near the drip tip outlet, which can effectively prevent condensation from entering the mouth. So far, I haven't experienced any condensation.    　 3. The Suck Suck Fun serves the purpose of an RDTA oil chamber but can be combined with any bottom-filling dripping atomizer, making it compatible with any box mod, which is really great! It instantly turns all box mods into bottom-fill devices.    　 1. Quality control needs to be improved. For example, after the first wire installation, I couldn't find the atomizer and had to loosen the bottom positive screw a bit. Also, the contents listed on the packaging do not match the actual items.    　 2. The atomizer's air control relies on the air holes on the cover and the air slots on the base. Since you need to observe the cotton's oil level, you have to frequently remove and insert the cover, which requires readjusting the airflow. If there were an additional layer inside the cover to adjust the airflow with two layers, it would eliminate the need for readjustment when removing the cover. When it's time to refill, it's not difficult; just cover the air inlet with your finger and suck it in.    　 3. The Suck Suck Fun's oil guiding is not very smooth. With three different air hole guiding strengths, using the hole with the most guiding strength doesn't allow for much oil. Actually, after taking a few puffs, closing the air inlet and sucking in a puff to refill isn't too troublesome, but the strength of that puff is hard to control. If you're not careful, you'll suck up a lot of oil, and opening the atomizer's air inlet will cause some oil to leak out.    　 4. The Suck Suck Fun does not have a top cover, which easily leads to a layer of oil on the bottom of the atomizer. I completely don't understand the benefit of this; it just saves a layer of metal cost.    　 5. The Suck Suck Fun has a diameter of 25mm, while the Two Dogs has a diameter of 24mm, which is a bit funny.    　 I like the design of the atomizer; the wire holes are large, compatible with wide-bodied wires, easy to install, and the chamber space is not small, allowing for a large coil space and producing thick and rich vapor. I feel the atomizer is quite mature.    　 The Suck Suck Fun is compatible with any bottom-fill atomizer and any box mod, which is an important direction for the future. However, since it is a new product, it has many shortcomings. I hope that if there is a second generation in the future, there will be significant improvements.
