...'Engineers' who won't ship out a few lab samples to customer and your Average Slob (me) to try out 'fore rushin' 'em to Production.
Take the toolbox maker who insists on a hinged caryin' handle. Gee fellas, anyone out here coulda tol'ja it'll leak at the pivot. Any one of us, me included, coulda suggested six different ways it' coulda been avoided, at a cost to each box of a fraction of a cent. In short, owing to the apparent incomptetence of the design " 'Gineers," it either doesn't work, it could easily have been made better, or it could easily kill you.

Like the Front-Gate maker shippin' thousands of gate kits with a note to the effect that once assembled,
'...it can kill'. The average technically-inclined 8-year-old could easily suggest a half-dozen easy ways the 'Engineers' could have prevented this, at only minimal prod. cost.
Not only don't they talk to their customers but not even to each other;, so, guys, set some sort of standards. F'rinstance there's the dripper, a watering gadget, rated in gph, gallons per hour [or God help us. liters per hour], each mfr, of which there must be dozens of not hundreds, id'ing the drip rate, typically 1/2, 2, 4, 8 gph, with its own color code. Fellas, why not adopt the 'neers's' system of resistor coding [where It's become a real challenge, codin' by the resistor color code:

[Thus yellow = 4 gph. But how about 1/2 gph, or 12 gph? Well, your 8-year-old will point out that most drippers are made of two plastic parts, snapped together….. Gee, 'Engineer' fellas, why'n'
you think of that ??
