The RTA’s main selling points are its large 25mm flavour tank and its ability to produce large chunks of vapor with low power input. The product has two tank sections, each holding 3.5ml and 5ml respectively. It is available in a variety of colours and you can find it in most retail sites around the globe. You can get it at Element Vape at $36.95.

Build Quality and Design
The Wotofo Profile Unity RTA looks and feels like a well-built product. The finish on the RTA is impressive for this price. The company has also done a good job with the inside of the tank. The machining is not top notch, but it is acceptable.
The tank is just the right size. Not too big and not too small. Its height is only 44mm with the 5ml tank. The drip tip has a Goon style design which feels good to use. The tip can also be used with some tips without O-rings. However, I doubt you will want to swap. The design of the RTA drip tip means the tip is essentially part of the tank.
The design of the top cap is also simple but effective. It only requires a 1/3 turn to remove the cap. However, the fill pots are too narrow. This means that you have to be very careful while refilling to avoid creating a mess.
The threading on the bottom deck also causes some issues especially when putting back the tank. This forces you to turn the tank upside down and put a lot of care into screwing it back in. In addition, the machine’s design forces you to remove the tank before you remove the deck.
The Wotofo Profile Unity RTA borrows a lot from the RDA when it comes to build deck design. The only difference is that the fluid can fill up from the bottom and the top with the RTA. The deck is designed to fit in with different multi-strand coils.
However, most coils will struggle to fit due to the large wick pots. The mesh coil is designed to fit in with the conical chamber.
The clamps that hold the mesh strip are designed to hold it in a sort of semi-circle. They are different from other products in that they are not spring-loaded. You can easily unscrew the clamps to release the strip.
The ceramic platform on this product is the same as with the RDA. It is designed to push up against the cotton to hold it in place. The mesh strip design often causes the cotton to sag once it gets damp with juice.
Coil Installation and Wicking
The mesh strips included have a resistance of about 0.13 ohms. You can use strips from the Wotofo Profile Unity RTA, but they have a higher resistance. Wotofo also includs a coil rod to assist with installation. In addition, the instruction manual is detailed enough to assist you with the installation.
All you have to ensure when installing is that the mesh strip forms a semicircle. Ensure that the clamps hold the mesh trips in place using the screwdriver. The risk involved with a loose fit is that it can cause the coil to ignite if it is not in constant close contact with the cotton wick.
Shaping the mesh is easy, and it will only take a few seconds. After it is safely locked in, give it a couple of 10-15 watt pulses to give it an even glow. You can apply your own knowledge when it comes to wicking, but it won’t hurt trying out the suggested method first.
The cotton provided by Wotofo has the right thickness for tight wicking. The instructions provided by Wotofo should ensure that you have a good fit. First, you need to cut the cotton at a 45-degree angle with the wider part at the bottom.
The bottom portion should be tucked into the ports while the top ports should be fluffed. You should ensure that the cotton doesn’t bunch up at the bottom of the well. This will give enough space for the juice to flow.
If you get everything right, you will enjoy the performance of the RTA. The vapor and flavour are of high quality. In addition, the flavour gets more intense once the mesh breaks. The RTA is a juice guzzler. You will need to break out the juice bottles while using the RTA.
Therefore, it is more convenient for you to use the 5ml tank section. The performance holds up with normal usage. The wicking feeds the juice the cotton effectively if you wicked effectively.
You should try to stay within the recommended 60-70 watts for optimum performance. You will soon start getting dry hits if you consistently use higher watts.
The RTA features two sets of airflow holes. The adjustment ring is tight enough to stick to the position where you’ve set.
Even when fully open, the airflow has a noticeable restriction. However, the airflow is smooth, quiet, and efficient. The airflow is designed to focus airflow on the mesh.
The RTA produces mildly warm vape at the recommended 60-70 watt range with all the holes opened. However, the warmth goes up as you close the holes. To counter this, you can decrease the wattage as you close the holes. This way you will continue to get nice and warm vapes.

This tank combines everything you would want in a vape tank. It is easy to put together, and the vape quality is amazing. There are a few design faults, but they are negligible considering the tank’s performance. The wicking process is the most annoying part of this machine. You have to get it just right to avoid damaging the mesh.
It is safer and easier for you to wick using the method provided by Wotofo. The bottom line is that you ensure that the wick is tight at the mesh and the tails on the top half are fluffed.
Just get the wicking right, and you will enjoy this RTA.
