I was debating between the Hip Hop and the Pioneer DC plus and decided on the Hip Hop because of the mounting and the price. This machine is built very well with the only non-metal pieces being some of the knobs and the ands of the support posts. The machine came very well packaged and nothing looks used or damaged. The one problem I encountered however was that the top of the string gripper was jammed down so I had to unscrew it and put it back on the right way. Mounting: [/URL] Mounting the racquet is quick and easy with the two knobs. The top black knob is for the sides and the bottom chrome one is for the center post. After my fist racquet there was no frame distortion based on my eyes. Clamps: [/URL] After using this machine I would love to try spring assisted clamps to see how much better they are because I could not imagine any clamps easier to open and close. I never had a string slip nor were there marks on the strings. Tensioning system: [/URL] The clutch worked great without any problems. I was a little concerned about the rotational gripper rather than the linear gripper but I see very little effect on the string. Turntable/Brake: The turntable is very heavy and is very solid I, I never had the machine tip on me. I was not expecting much from the brake nor will I need it very much because of the lack of O3's that I will be stringing but it worked very well for the O3 that I strung, I could not imagine having to string one without it. [/URL] Over all my first string job went well after a bit of trouble at the beginning but in the end it probably took me about 2 hours. I would like to thank all of you for helping me with my decision and especially YULitle for your great videos. (I don't think I could have tied any knots without them) I messed up on one of the crosses but thats way I used a Walmart frame that will probably never see the court again. If anyone want to see a pacific picture of something let me know.
