I've recommended both of these items before, but they are really great in the sense that WD-40 and vice grips are great. Once you use them you can't live without them, plus they are both simple and well made.
The first is the fig8 cord organizer. You've been there - stuff the mp3 player or phone into your pocket and out comes a tangled headphone cable a few hours later. Sometimes you wind the able around the device and may even tie it off with a rubber band. These are tacky and unsatisfying solutions. The fig8 is just that - it gives two posts that make it easy to wind the cable in a figure eight fashion and then snap a cover down to make sure everything stays in place. The cable easily pulls off completely tangle free. Watch the video on the site.
Highly recommended! There is a discount for multiple units and these make really great gifts. Very clever and you won't be getting another tie. It is very well built and should last at least ten years - much longer than any phone or mp3 player.
They go for ten bucks.
I've mentioned the second item too, but it is too good not to recommend.
Thanks to mass production and Levittown, it turns out most kitchen countertops are about thirty six inches high. Most of us don't think good posture in the kitchen and many of us don't really cook anymore, but if you have above average height and do a non-trivial amount of food preparation, you probably experience some back pain.
Researchers have worked out optimal heights food preparation for standing postures and the three foot counter is just awesome for people in the five foot four to five foot five range - the average height of an adult female in the US in 1950 and 2010. Shorter and taller folks encounter problems.
One solution is a raised height cutting board. Colleen has one that gives her a forty nine inch high working surface, which is perfect for her stature. I'm quite a bit lower than her, but mine is set to about forty two and a half inches and is perfect for me. Mine is eighteen by eighteen inches and hers is eighteen by twenty four, giving her an extended platform -- a second countertop so she doesn't have to bend between her working surface and the real countertop.
Colleen has some videos on her colleenification blog. Both of ours were made by AWP Butcher Block. You can get whatever size you want and Colleen's blog has measuring instructions. A fifteen by fifteen inch model that is six inches high is something around $120, but call for a quote - they are extremely friendly. The hardwood construction is excellent.
We've found you don't give up any counter space as you can store stuff under them.
Don't let her two meter height suggest that your husband or father may not be able to use one. Anyone over about five nine or five ten probably could use something like this if they cook.
