Tile is the little tracker that gave every forgetful person hope that they

And after shipping more than 300,000 devices since it began in May (that’s
a lot of lost keys), the company is now announcing $13 million in funding

Once upon a midnight dreary, while I pondered, weak and weary,
Over many a quaint and curious volume of forgotten lore,
While I nodded, nearly napping, suddenly there came a tapping,
As of some one gently rapping, rapping at my chamber door.
"'Tis some visitor," I muttered, "tapping at my chamber door —
Only this, and nothing more."

NOS can great increase horsepower because:
1)It provides lots of oxygen for the engin to burn. N2O -> N2 + O2
2)As it changes from the compressed liquid form into gas, it absorbs
a great deal of heat. So it super-cooled the engine. As the engin

to be, which means even more stuff to burn!

这是第11代卡罗拉，为了吸引更年轻的用户而非维持以往用户，继“Avalon”

带大开口的保险杠等为特点，并搭配大幅膨出的翼子板以及向后平缓下滑的C柱。
新款卡罗拉的外形尺寸为长4639×宽1776×高1455mm，与上代车型相比车长增
加99mm，车宽扩大16mm，但车高降低10mm。轴距为2700mm，比上代车型长100mm。由于
轴距更长，因此后座臀点后移了75mm，另外还通过减薄前座靠背，使后座乘坐空间变得

发帖数: 30533 | 33 I have played with both TT bandit and LM Radical.
Head heavy and light is almost the same thing. A heavy racket is almost
always head light.
What you heard is correct. If you use SHBH, having a heavy racket is
almost a must. Using heavy racket, you will swing faster than before
but with lower accuracy. You serve faster and with more errors. Your
forehand is more powerful but can't defend as well as before. Your
volley will be crap.
18*20 is denser, so it's harder to spin but easier to control.

babolat Drive GT series but $100 cheaper. I hit with both, but can't tell

For beginners, the $79 BB V1 could be a good choice. Volkl V1 is a classic
