i saw this product today on the internet,everthing you need to know about mosfets 
Enhances the electricity gun reaction time. Trigger switch after long-term processing high-tension current brings about the flame, the carbonization, the resistance rise, finally trigger slow reaction. But most major problem not in that little resistance rise, but will lie in the carbonized phenomenon to further cause the switch metal to wear down, bringing about bad contact, aggravating flame carbonization? Continue the vicious circle like this, will happen one day the switch wears down to cannot contact, when pull the trigger the response (has not used lithium electricity even more should specially to use fet, because current ratio is bigger with cable telegram, electric power switch good wound, even more will be actually able to display with fet the lithium electricity potency). But in MOS in the FET electric circuit, the trigger will only hold the post by the micro electric current sends a message the role, will swing controls the field effect tube processing high-tension current, will avoid this question.
Because time pull the trigger in battery's electric current is released all of a sudden, the amperage may strengthen largely in the flash, leads the electrical machinery violent revolution, has the possibility to tear to pieces stiffly the tall ladder. MOS the FET electric circuit the excessive electric current filtration, avoids this crisis.
When pull the trigger, the switch is not contacts completely in physics, therefore the electric current is unstable, presents the vibration phenomenon, reduces the whole operation potency. MOS the FET electric circuit's field effect tube puts through when the electric circuit vibration is very small, may maintain the smooth electric current supply. Reduces the part loss and the potency waste greatly.
- miserly electricity
- not carbonized for switch metal
- all battery is suitable
In all seriousness it looks cheap for what it does but if pushed with long bursts or high current it will most likely fry itself.I did have some shims that were the same brand and the hole in them was not big enough for the gear shafts 
this is the link to the product in question

In the product title it seems to suggest it can be set for controled burst fire for the number of shots of your choice,however it does not say that in the text or what the perameters are for any programmable functions only that it will improve the electrical efficiency of your gun and save your trigger contacts.
Well that clears that up nicely , we should sticky it in technical help section

Give me a big enough hammer and a place to stand and I could fix the world.
i'll kill a man in a fair fight or if i think he's going to start a fair fight or over a woman or.......
a problem shared is a problem halved ,but an advantage shared is no advantage at all
if a job's not worth doing then its certainly not worth doing well
Yes apparently Chinese instruction manuals have formulated a new language ,it's called Chingrish,saves them paying out for a proper translator .
Must strip down all my gearboxes and inspect them for Flame Carbonization damage 
And I'll check to see if my fets have moss in them !

If Stanley Unwin was still alive, he would have understood this, and his translation would have been worse!

Actually i should keep quiet because that guys English is way better than my Chinese.

But you are not explaining tech professionally to customers !

Might have to get one of these mosfets, I want my electric power switch good.

Mosfets are only really needed in guns which do single shot alot. I have had switches for over 10 years look good as new on guns where i just use full auto.
You can get some interesting programming ones which can control rate of fire, or adding things like burst fire.
