Ehpro Samurai from Canvape
At the right is the box the Ehpro Samurai is packed in. It's pretty basic and includes a mini philips screw driver, spare O rings, two spare screws, and the Samurai RDA with your choice of two caps. The larger drip tip cap is actually slipped over the smaller version to maximize space in the box.
Taken all apart, the Ehpro Samurai looks like:
I am going to post a series of pictures to show what the unit looks like as it is assembled:
The picture at the left shows the base with the outer tank sleeve.
This one shows the air flow control ring around the mid section of the outer tank sleeve..
This one shows the assembled tank with the larger drip tip (it's one piece) threaded in place.
This one shows the assembled tank with the smaller chrome top with POM drip tip (it's a two-piece system) threaded in place.
At the right is the coils for this build. The coils are 24 gauge and combined provide 0.2 ohm resistance. What you want to notice in the picture, though, is the air flow chamber at the bottom right below the coil. That air flo chamber shows a slot ith two holes. Further down the base on the vertical plane is a slot, also with two holes in it. That is where the air flows for that coil. There is an identical air flow chamber for the coil at the top of the picture.
The deck base is actually two stepped. The lower section is your juice well, the upper "step" is the top portion where the air flow is closest to the coil. You want to wick the coils so that each end wraps under the coil (towards the center post). This is where you need to be cautious and avoid having the wicks too close to the air flow channels so you don't end up with leaking. In the time I spent building the coils and wicking, it's the tucking portion that took the most time. You want to tuck that wick carefully to avoid that air channel and flow liquid away from that area – yet get enough liquid to the coil.
The post screws are nice and smooth. The post holes are a generous size and adequate for a twisted 24 gauge build – although the center positive post might be a bit on the tight side with four strands in it. The holes are also not offset, to get your coil horizontally level, you will need to do some bending of the legs. The easiest way to do that is to do tighten the legs, and then manipulate the coil into horizontal level.
At the right I am test firing this and getting a reading of 0.2 ohms. I was pleased with this build, the glow was even and tight from the center out. Both sides were equal.
I ended up wicking this twice. With the first wick, I ended up with an off-taste and decided to clean it thoroughly a second time and re-wick. After the second wicking, the flavor was quite good and cloud generation was excellent.
This is a versatile tank. You can move the coil closer to the air flow chambers to get a warmer vape and more flavor. Move it away to get a bit less flavor and more clouds.
I'm showing the Ehpro Samurai at the right mounted on an V3Tronix clone.
I like the look. In practical use, though, I found the liquid well does not hold a lot of liquid: 15 drops at the most.
And, one upside. The Ehpro Samurai has an adjustable copper 510 connector pin. The transfer of power to the coil shoud be quite efficienct.
The build quality is excellent. The threads are nice and smooth. Although the air chamber and holes look complex, this is actually quite a simple tank system with massive air flow.
So, what's the verdict? Is it worth it? For a three post atomizer, this is among the best. I really like the wide open drip tip ... this is well beyond wide bore, it's nearly straight pass through. The Ehpro Samurai is a flexible and very versatile dripper tank. The only issue is that the large POM top was a little bit rough on the edge. Ah, but, the convenience of just dripping your juice straight down that large opening makes this convenient and well worth it.
