Ko-ken Tools 3/8" Sq.Dr. Ratchet Handle 72 teeth Flexible Head Length 178mm Quick Release Z-seriesKO KEN QUICK RELEASE RATCHET Ko ken ratchets are known for their very low backlash, small head sizes, and high torque ranges. We designed the new 72 tooth ratchet without compromising on our traditional strengths. The patented design of the 72T combines the low backlash, small size, and has a 10% higher torque limit in comparison to the 36 tooth ratchet. The legacy 36 tooth ratchets move 10 degree click. The new 72 tooth ratchets move 5 degree click.

KO-KEN QUICK RELEASE RATCHET

Ko-ken ratchets are known for their very low backlash, small head sizes, and high torque ranges. We designed the new 72 tooth ratchet without compromising on our traditional strengths. The patented design of the 72T combines the low backlash, small size, and has a 10% higher torque limit in comparison to the 36 tooth ratchet. The legacy 36 tooth ratchets move 10 degree/click. The new 72 tooth ratchets move 5 degree/click.

The design changes include moving from the single pawl of the 36 tooth design to the patented dual pawl of the 72 tooth design. The dual pawl 72 tooth design utilizes a single spring. We took four years of testing to perfect the low spring pressure needed to maintain Ko-ken's hallmark low-torque backlash. The finer 72 teeth design creates more surface area contact with the gear; thus, it has a 10% higher torque upper limit.

Snap closure watch.
Not the best quality or materials but remember, it’s extremely inexpensive.

Nice accessory for anyone to wear, goes well with any style
Durable material makes it easy to slip onto any wrist (plus, adjustable strap, so there's that too). The fact that the watch actually WORKS is an added point, considering most of these out there have the clock as a graphical enhancement rather than an actual working point to the piece. The title of the item says for girls, but whoever you are out there, wear it despite what it says. These sorts of accessories are multi-person usage. It looks cool with any outfit design, too.

Cute! Poor battery.
This is super super cute. I love the layered bangle look and the hanging charm and the dainty little watchface. It's very comfortable to wear. I knock it down a star because the battery it came with only lasted 3 months - I know it was an inexpensive watch, but I was disappointed with the battery life.

Cute, but too small
It's cute, but kinda cheaply made, and it doesn't fit my wrists. So, I gave them to my niece. She loves them. (This one and a similar one that I bought)
