No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

Great addition to my sewing table!
I ordered two of these to give me a little more room on my sewing table. One for the backside and one for the left side. Worked out great! Very sturdy and not hard to install (followed directions). I just extended when I need room and fold when not in use. I would recommend these to anyone who just needs a little more table/room.

Not very sturdy
The oak that this is made of is very nice. The little bit of extra counter space is nice. The problem is the bracket to hold it up is kind of small and flimsy, so the shelf won't bear much weight. It will be ok for putting light things on. Also had a problem getting it to hang flat in the down position.

Don't know about these items and ratings have nothing to do with product because the next day air has been sitting in the UPS building for a week now.

No quality control.
Look at other options. Received with hinge already attached to the wood, at an angle. Tried to contact seller, no response. I fixed it myself. Rather than having hinge attached they should just let the buyer install the hinge. Made in Vietnam.
