I found their "Low Boy Paddle" to be of poor but satisfactory quality. I was initially put off because the key which requires assembly didn't have the correct parts but to the company's credit, they promptly supplied the missing parts from a list I emailed them.

I found the use of using the tops of machine screws as key contacts to be troublesome but they worked adequately but not pleasantly, but I time I got used to the clunky feel.

I had a friend,  Fowler "Barney" Norris, W3MTE (FN), a former CIA Morse Operator, who was an excellent radiotelegrapher who worked for Tropical Radio Telegraph (TRT) at Slidell, Louisiana Radio, WNU and he was both fast and accurate. He used a homemade kit from two J38 keys mounted next to each other. All his motions were up and down, using minimum finger motions. TRT had the highest standards for Morse operators, minimum perfect copy requirements for five minutes without error was 35 WPM. 

The key was usable but disappointing in quality.

A fine quality single-lever paddle is the American Morse Equipment Mini-B: American Morse Equipment - Mini-B Miniature Single Lever/Sideswiper Paddle which is well-adapted to portable use. I attach it either to my transceiver or to a clipboard using 3M Dual Lock. If a connecting cable fuses the left and right terminals, it can be used as a cootie key. For use in freezing weather, I cover the paddle handle with heat-shrink tubing.

Chris…Re: Vibroplex Vibro Keyer. Although it lacks some precision, flash and exotic metals that other higher buck single lever paddles offer, I have always found it to be easy, pleasant and comfortable to send accurate CW with…. As long as contact spacing isn’t terribly minuscule…

I mounted my Kent single lever paddle on a 6mm brass plate with a wood spacer cut away for the wiring between.  I prefer terminal posts rather than a captive cable, so I purchased them from Kent  Keys.  Finger piece is Teak.  I prefer this key to a leaf spring (saw blade) type key, although I learned with a home-brew saw blade key.
Dot and dash contacts are shorted underneath the key in the spacer.
If I wanted a little spring action, I would put the leaf spring between the lever and the finger piece. 
I find it works well as is.

I found the width of the combination of the button knob and the paddle knob to be too great for comfortable sending in cootie mode, so I had someone make me a single knob with a inset fastener with a special U shaped two prong spanner to tighten it.  Much better, someone on the Internet was selling such a modification but I could not find it right now.  Maybe it's gone.  Maybe Vibroplex will make one.
