I was lucky to buy one from a guy I met at a pro-am for 25$ that had a broken clip on the bottom that didn't even serve a practical purpose.

I let my 13 y/o cousin have it. I must say, the crafsmanship of it was excellent. The entire area that holds the ball was plastic all around, like a casing, unlike my 2-ball roller that has cups at the bottom of the bag and a velcro strap to separate the balls. Very sturdy looking bag.

The KR 3-4-5 is built very, very well. I've lugged my around for the better of part of a year and it's held up extremely well. It's money well spent.

Hey Group,
 Well, it came in after I went to my Friday night league so as soon as I came home and saw it still in the box that it was delivered in I thought "Oh!-crap!!" it has to be broken since the box was very bent and squished.

 However, after I opened up the box the roller was in perfect condition and still in its deliverey plastic wrap.

 Now compared to my Columbia 4-roller which is falling apart its very well constructed, I mean this puppy is well built. It's physically smaller though which I wasn't aware of but that doesn't mean anything since I only had that other 4 roller to go by

 A couple of things which are better IMHO then its counterpart is:

 a) 3 wheels to roll on and not the standard two.
       which means a lot to me since I'm always lugging it in and out of my
       house since I bowl 4-5 times a week so I need durability.

 b) somewhat smaller
       nice for being in the house or the back of a car

 c) the front accessory-bag on the upper ball carrier is sewed on
        my other one was Velcroed on which I didn't care for since I can lose
        anything if given the time

 d) seems to be more more pocket space
        ok, this is weird, after moving out all of my accessories from old bag
        to new I still have a lot more space...maybe its just me!!

 e) a nice 5 yr warranty

 Ok, boys and girls thats all for now if anything weird goes wrong I'll be sure to report back in with my findings, but so far this is really one sweet 4-ball roller.
