Hi Clinton, great questions:
Both seem to hold the same amount of drops so I think it's just a matter of preference. One elderly customer did say to me "she has enough wrinkles around her mouth so a flat cart suits her just fine"
We go
through a lot of
batteries and although we specify that we want blue LED's for every colored battery and Amber for the white ones, the manufacturers still sometimes supply a mixed batch.
So the best way if you have an LED color preference is to email me
just before you're ready to place your order. At least then I can confirm!
Cheers
Ed.
