Here is my video review of the Buzz pro that i purchased from http://www.liberty-flights.co.uk
I really did want to go into a little more detail with this video but i am limited to 15 minute video so i was unable to mention everything. These are the notes i made before creating the video so i thought why not post them as well.
Very nice chrome finish to the top cap, but if for any reason you feel the need to unscrew this part be very careful because underneath is the electronics that support the built in safety features of this device and the wires. When i received the buzz pro the top cap was slightly loose so i just tightened it up and left it alone. I feel there is no need to unscrew this unless you are having an issue with the connection.
This one is a 510 connection but they are available in different connection types. Hopefully you will see the screw that acts as a top pin but also it holds the wires in place underneath the cap. I have read that the connection is sealed so you can drip using this mod without having to worry about juice leaking onto the electronics.
Also here you will see that there is a groove on the top cap as well to catch any stray juice if you do use this mod for dripping.
Again there is a nice chrome finish to the bottom cap but as you can see the threads are plastic. I was expecting them to be metal like most other mods. The chrome plate as you can see the screw goes through the plastic then the spring and is tightened up in this small nut.
Now to turn this mod of you have to turn this bottom cap anti clockwise as if you was undoing it about half a turn and over time this can work the nut and screw loose. So make sure to keep your eye out for that.
The over all finish of the body is of high quality. The texture is not smooth but not rough either its hard to describe really but you will not have to worry about the mod slipping out of your hand.
The button is small and recessed as you can see and is made of rubber. It takes a little time to get use to the feel of it but it works flawlessly. For me the placement of the button is spot on, it just feels in the right place when you use it. Also it clicks when activated.
The hit control as the manufacturer call it or where we adjust the voltage is just of to the left hand side of the button as you look at it. I really thought this would be an issue as i was worried about myself catching the wheel with my hand whilst activating the button. However this turned out not to cause any problems and i have never accidentally moved the wheel. The wheel itself is easy to move but stiff enough that if you do catch it by accident it wont move.
Hit Control - No Load
Also you should be able to see a red light, this shows that the mode has power. When you push the button the red will turn blue letting you know that its all working ok. And when you turn the end cap half a turn the red led will turn off letting you know that the mod is now off.
The screw just above the hit control i think is there to hold in the electronics so i would recommend leaving that alone unless you know what you are doing, and i dont so i will take my own advice and leave it be.
There are 3 vent holes on the body as you can see to let any gases escape if a battery decides to go postal and also there is a small vent hole in the bottom cap.
Finally as you can see the mod comes with Buzz Pro and the serial number of the mod printed nicely on there.
2 x AW ICR 750mah Li-ion Protected Batteries.
0.86" in diameter
And it weighs around 3.5 oz
I have been getting around 12 hours out of the batteries at about 4.2 volts, this will vary depending on how much you vape and at what vaultage.
Over current protection
Over temperature protection
Reverse Battery protection
Lately there has been a lot of discussion again about stacking batteries in mods. As long as you take care and take no chances you should be fine. The buzz pro as mentioned earlier has built in protection that will shut the mod down if it detects something going a miss.
I do the following, i label my batteries as pairs 1a 1b and so on and they will stay together as a pair until one packs up where i would bin both. I will always charge them as a pair and use them as a pair. Also i rotate them when in use meaning 1a will be on top then the next time they are used 1b will be on top. This will even out the wear and tear on them evenly as the battery on top takes a lot of hammer.
Never take chances, if you feel the battery is just not right bin the pair. Any rips on the battery casing, bin the pair. They are cheap and replaceable fingers hands and lives are not.
All the best,
