The Bullet mod is a full-mechanical device made in the Philippines. This was purchased last July and has seen constant use. It is made of three tubes that allow you to use 18650 down to 18350 batteries. Below are images of the different configurations you can use depending on the battery you wish to use.

| 18350 Configuration |
In 18650 mode, all three tubes are used. It is worth noting that this device will work with nippled and non-nippled batteries. The first and second tubes are connected via threads that one can use to adjust depending on the length of the battery. In 18500 and 18350 mode, the third tube is not needed.
I am no expert in metallurgy so I cannot say what type of steel is used. What I can say that it has been dropped on hard surfaces such as concrete resulting in marks where the metal hits hard surfaces. Despite this, it continues to function and these marks are only cosmetic.
Above is a picture of the bottom of the firing button. For those who prefer to have a locking mechanism when storing the device in a bag or pocket look for another device as this unit does not have one. The spring used in the switch assembly is stiff enough to prevent accidental firing and when stood upright there is enough clearance so that the switch does not touch anything.

| There is a plastic insulator that can be removed for cleaning and prevents any other part of the battery to come in contact with the firing pin. |

| The pin is made of copper and does require polishing every now and then. As stated earlier, this device has been in use for about six months and the pin hasn't been polished yet. Even without polishing, it manages to fire consistently. |
For cleaning purposes, the switch assembly breaks down into four parts. The spring is quite stiff and can resist casual pressure. That said, at first one might find it too stiff when brand-new. It does soften over time. One thing I noticed is that the switch will sometimes rotate and fall off if one is not careful.
The device uses a 510 connection and a copper pin for good conductivity. The pin can be adjusted somewhat using a pair of pliers so flush-mounting an atomizer is possible.
Conclusion:
Overall, this device works very well. It is durable enough that dropping it won't damage the device and simple to use. It has a hefty-feel that I personally like and fires all the time. Things I don't like are the tendency of the firing button to loosen and the need of tools to adjust the 510 pin. Finally, one may be put off by the fact that it has no locking mechanism and only a stiff spring prevents accidental firing when inside one's pocket or bag.
Despite these slips, I would buy another one should I lose this. Why? It is easy to use, I do not need to think of whether it is locked or not and it's price is quite a bargain.
