Here are some of the physical characteristics and technical specifications of the Epila Laser Hair Remover model SI-808.
My own observations:

Length: 6.5 inches
Width: 2 inches
Thickness at bottom end: 1 inch
Thickness at top (laser) end: 1.5 inches
The unit is of similar shape and size to an older model cordless phone. I don't know the weight, but it is lighter than my own recent model Uniden cordless phone. Most of the okay sellers of this item include photos, depicting the exact unit that I own.
On the underside of the unit is a power button and a function button. The function button, when pressed, switches the unit between low, "middle" (medium) and high power. I usually use the unit on high, because I don't feel the "snap" when I use it on low or medium. However, since my eyebrow area has proven to be sensitive, I will try lowering the power when using the unit in this area.
At the laser end, there is a "touch bar" which is a small protrusion that touches the skin, keeping the laser diode the correct distance from the skin.

Length of touch bar: .375 inches
