You really need a good 4 inch tee (or longer) to get the ball high enough off the ground to find the sweet spot of almost all new x-large driver club heads. With that in mind, PGO's might be a little "stubby". I see his point, but with the way tees fluctuate in length (and this is no joke) I don't think it's necessary to have a tee in the logo...especially with the name being "BIO GOLF TEE". The originals aren't all that bad -- don't bin them yet.
On a somewhat related note, I'm an avid golfer, and I just got these:

I tee off in an hour for my second round with them...
