"These gears are insane! They work great and I haven’t managed to even scratch them even with manny mistakes on my part just to list a few of my mistakes.
Had the motor to far away and the motors teeth were shredded but these gears were not even scratched! they just had to be cleaned
I had a plastic piston in at the start and the teeth got caught to early it destroyed the piston but no damage to the gears(my mistake I should have put in a stronger spring to get the piston back into place faster)
So what I have to say is the durability of these gears is crazy but you do need to be careful and set up your gearbox right or these gears will shred some parts. in all 10 of 10 on durability and 10 of 10 on ease of use (if you don’t count my stupid mistakes should have done some more research first)

"I have the 14.09:1 gears, sp140, and an ASG 28 TPA motor--instant response but plan to get 10:1 for even more response.

Pros: indestructible if shimmed right, many options of ratio on the market.

Cons: price

"I've had these gears in my JG SL-8 for almost a year now and they ARE the best gears I could get. By far. They do take some trial and error to get them shimmed right and running at optimum speed. I changed out the bushing to Modify 8mm ceramic bearings and have this coupled with a gt-45000 motor from 6mm shop. I get about 38 to 41 RPS depending on the charged of my 11.1 lipo.

I could not ask for a better setup. Warning though..If you use these, make sure you change the piston to a full steel tooth piston and dont skimp on other internal parts.

My sl-8 is now a full SAW and it is terrifying. I HIGHLY recommend any gear from seigetek. I'm pulling an m120 spring with a bore up kit and I get about 328 FPS with 0.25 BBs. Only issue I have had, is I put in a Gate Titan mosfet into a CNCed gearbox. The issue I had is the selector plate kept breaking on me. These are NOT for the faint of heart, but if you want a solid build that can scream, then these are for you.

"these arrived in great condition and these gears are the best in the world in my opinion (at least for now since its 2017). these gears can handle a prommy sp200 in my DMR. Ive shot about 5000 rounds and I reopened the gearbox to check everything out. THE GEARS HAD NO SCRATCHES OR DINGS OR ANY FORM OF DAMAGE AND IT ALSO DIDNT DAMAGE THE TEETH ON MY THOR2 PISTON BY ANGEL CUSTOMS. if you have the money for this investment then do it!! you will not ever be let down in any build youre doing with siegetek gears. BUY THEM IF YOU CAN, YOU ONLY NEED ONE SET THAT WILL ALMOST NEVER NEED TO BE REPLACED. (im still trying to see how long they last so i will update this review on a later date)

"The best gears money can buy, but not for noobs!

Please, if you are new to tuning your gearbox or are a nervous tech, steer clear of these gears.

IF however, you are experienced or know someone who's experienced, then these are the gears for you. Once you buy these gears, you'll never need to buy another set again because they are the strongest gears you can buy and can handle anything you can throw at them. Just be sure to balance everything properly and use high quality parts along with them because they will annihilate substandard parts.

Pros:
Everything

Cons:
High level of skill required to install
High quality parts required to be used in conjuction with gearset

"These gears are great! I have my setup running these 14:1 gears and a Promy M150 with a JG blue motor and have had no problems! The trigger response I get with the gears is insane, the moment i pull the trigger the gun fires. These are the best of the best, they sound great, and mesh better than any other gear-set I've used. When you make a high stress setup these gears are a necessity. Another great feature is the anti reversal latch spots are just the teeth of the gears and lock the latch in so it doesn't come out for no reason. Great gears, will buy again!
