The Lab 50 is a high-performance 18500 mech mod based on our robust uni-tube design. Picking up where the Roller and Dingo left off, the Lab is a sturdier, simpler and easier-to-use top-side-firing mech mod. With its refined, sturdy switch and absolute minimum number of body parts to fiddle with, the Lab is a high-efficiency device with performance and safety features unseen in current top-firing designs.
The simplicity, ease-of-use and performance of the Lab comes with a style that departs from the strict minimalism of the Roller and Dingo. The Lab has a slightly more aggressive form which is still minimal and ergonomic, in line with its unique character.
The Lab sets a new standard in mech mod performance and safety, since it has been designed to include advanced safety features with a minimal or zero impact on dimensions or performance. Every Lab can be configured in 3 different bottom-cap-to-battery contact modes with different safety / performance characteristics (Springless-Fused, Springless-Direct and Spring-Loaded). Check out this section for detailed information about each mode.
All devices come with the Springless-Fused contact pre-installed, and include all parts necessary for re-configuration in Springless-Direct mode.
**Important**: All Lab versions retailed after October 1st 2016, do not offer a spring out-of-the-box. It is strongly suggested that the devices are used in fused or direct mode, for performance and safety reasons.
For micro-adjustments of battery space, as in fitting abnormally long batteries, or when using long Kick modules with 18500 batteries, it is recommended that you use a conductive spacer or a spring found in our parts section.
Spare PTC protection modules, silver / rhodium-plated springs (for Spring-Loaded Mode only) and other accessories and add-ons may be selected here or purchased separately.

This is a beautiful and perfectly designed mod. In 18650 mode it is about the same length as a Smok-e Mountain Vanilla 18650 bottom firing mod ie the lab is very compact!
The PTC fuse works perfectly and does not restrict battery choice – excellent feature and most reassuring.
I have tried it with a Kick 2. Works with no difficulty with18500 batteries (using the extension tube), but a bit of a squeeze in short mode, even using authentic 18350 AW IMR batteries, as I had to use the spring setup to get the battery cap flush with the body. I was a little concerned about getting a Kick out of the Lab once installed, but it is very easy – shake the mod and the Kick slides towards the bottom of the tube and can then be removed. No problem!
However, I have decided not to use the kick: the ability to have an 18650 battery in such a compact top firing mod, coupled with a Kayfun lite and the fused setup, means that I have possibly found the ‘sweet spot’. Very happy 🙂
Delivery from Atmizone was incredible: picked up by DHL in Greece at 4pm; arrived at my UK address the FOLLOWING day at 1:30 pm!!!!
All round, with its excellent website, I can thoroughly recommend purchasing Atmizone’s products: an excellent business.

Just received my (LA-0057) SS-M Lab a few hours ago, and I have to say this thing is a work of art. With the t16 extension for an 18650 its barely taller than my caravela bottom fire, simply amazing for a side fire mod. You get alot of bang for your buck here, it fits any battery with ease and no rattle. The flat rails on each side make it extremely easy to hold, and its uni-tube design makes everything look like a hybrid on it. The only downside I could find was the serial number on the bottom cap is at a very slight angle, and the button takes a small bit of effort to grip and turn, a knurled button in the future would be amazing. The new efest 35a 2500mah 18650’s do fit with the extension very snug.

This is my first experience with atmizoo,I have to say it has been a great one.The lab is a work of art and hits like a freight train.I purchased the 18650 extension but my efest imr batts do not fit.Not a big deal I have a couple of 30a sony batts on the way.Bottom line is the lab is worth every cent and atmizoo did a great job of shipping it to the US quickly.I will be back.

Now that I own 3 Labs(1Brass,2 SS-M) I think I am ready to give short review.
All my 3 Labs are top quality and machined perfectly:threads are smooth and everything else was flawless, too. I already liked the Lab on atmizoo’s pitures, but in reality it looks amazing! I really love the hybrid topcap that let you favorite atties sit so flush on the Lab that you might think it was a hybrid! I own a lot of Atties an was able to let everyone of it sit flush on the Lab. The finish of the SS-M version matches the Kayfun lite plus perfectly.
The button is operating flawless and I had no misfire so far. Maintenance has gotten easier with the Lab button compared to Dingos/Rollers, too. To see how easy that is just check atmizoo’s videos in the support section.
The bottom cap is designed very cleverly as it needs no spring and there is no need adjusting contacts. You just turn in the bottom cap till it touches the battery and you will never have rattling/wobbling batteries.
Voltdrop on the Lab is really not an issue on the Lab,it hits like a train. I did not notice any difference between using it with fuse or with direct contact, even with 0.5 Ohm setups.
Overall it is one of the best mods, if not the best that money can buy.
Customer service at atmizoo is awesome, they were alsways answering my questions very quickly.
