Ehpro Lock Build-free RDA Introduction

The Ehpro Lock Build-free RDA is the latest RDA from Ehpro, a company that has been around for a long time and many years ago was famous for making good quality mech clones, but in recent years has shifted over to making their own designs.

The lock is their 2nd RDA to release in 2018 and their first single coil RDA following up on the dual coil Panther RDA which I reviewed a few months ago. The Ehpro Lock Build-free RDA is a small 24mm single coil RDA with side adjustable airflow.

It comes with an included BF squonk 510 pin as well. It features a unique dual usage deck. It’s made to be used with the included notch coils which can be purchased separately as well and includes brackets for them like the Wanko RDA a few years back, as well has being a pretty standard postless deck too.

It’s available in 3 colors, Black, SS, and Blue each with a black resign snakeskin 810 drip tip.

Initial Impressions

When I first got this RDA, I felt a blast from the past as it reminded me of the Wanko RDA which came out in early 2016 that was the butt of many jokes using a fuse like coil system. The good news about the lock is you aren’t limited by using only those coils (the included notch coils) but it also has a postless deck to use your own coils on. Outside of that it was a pretty standard RDA so not much else to mention.

Build Deck and Wicking

Let’s talk about the build deck now. There are 2 parts to the build deck. Part one is using the included notch coils which is simple and easy to install in the brackets. It’s just like the Wanko or even the notchcore tank recently released by Joyetech. Just pop it into place and then wick it. Unlike the notchcore they don’t come pre-wicked so you’ll need to use your own cotton and wick it yourself.

Part 2 acts as a standard postless deck. It can fit a decent sized coil and is pretty easy to build on if you are used to postless decks. There are 2 post holes below the notch coil brackets and it uses good quality hex grub screws which is nice. It’s easy to build on and lead length should be 3-4mm, you just drop them in and tighten the screws. Very nice and simple as I love postless decks.

Wicking is pretty easy overall. It’s an RDA so not much to do. You will be dripping or squonking on it. Just place your wicks into the holes on the deep juice well which is under the airflow. Really nicely designed juice well.

Ehpro Lock Build-free RDA Performance

Performance wise, I used it as a single coil RDA only as intended with both my builds and the included coils. I’ll start with the included coils which are rated 30-50 watts and .2 ohm SS316 notch coils. They are pretty overrated as once you get above 40 watts they will just be burned as it’s too many watts. 30-40 would have been a better range. Around 40 is where they perform best but even at that are really poor performing and lackluster and don’t have much in terms of good flavor at all.

For using my normal builds, my recommendation is 3mm ID however 2.5mm and 3.5mm also worked well. 4mm is a little too big for the air IMO. It’s a pretty versatile RDA that worked well with a simple round build, but really shined with a larger fancy coil build. Flavor is above average for a single coil RDA easily one on the better flavor producers on the market for single coil.

Overall Impressions,Details,and Extras

It’s a dual side airflow RDA that comes in from the side and goes through metal blocks on the RDA to hit the side of the coils similar to the Wasp Nano. The air holes are 3 small circles on each side . AFC however perfect and it’s easy to adjust the airflow. You just twist the top cap and It has knurling for grip and the top is shaped like a hexagon.

The o’rings on it are perfect size. It’s really easy to adjust the air o take off the top cap. It’s also on a stopper. It really just works well. It comes with a standard 810 resin snakeskin drip tip which are popular these days and looks really nice on it. It doesn’t come with any other tips however does include a 510 adapter so you can use your 810 or 510 tips on it. The drip tip fits great and isn’t too loose but also easy to get out.

The quality is really nice on this RDA. There is no threading outside of the post screws, and all the o-rings are nice and the right size to easily adjust air and to take off the top cap and put it on. It’s a 24mm diameter so wont overhang on pretty much any modern mod. The airflow is pretty smooth but can be a little loud if you close it down to 2 holes on each side and with 1 hole on each side can be pretty tight for DTL and a slight whistle.

It comes with a standard 510 pin as well as a BF squonk 510 pin to use on squonk mods. Looks wise it looks good, the only branding is the lock logo engraved on one side which I like. They also include a spare set screws (all screws are good quality hex screws), 2 notch coils, an allen key and plenty of o-rings.

Conclusion

So with all that said, do I recommend Ehpro Lock Build-free RDA? I don’t like to do a hard yes or no, this one I’m going to lean towards the yes. Not if you plan on using the included coils as they are no good, but as a single coil RDA for dripping or squonking it’s very good on flavor, easy to build on, and nice quality with an easily adjustable airflow. If you are in the market for one, this will be worth the look for sure.

I started vaping in late 2011 to quit chewing tobacco. over the past few years i got a lot more into the hobby side and buying and collecting a lot of gear. Fed up with the lack of good fair reviews i decided to start doing reviews late 2016 and haven’t looked back. I enjoy providing people with technical reviews that are fair and unbiased and from a place of knowledge to help them spend their money wisely.
