Light 3D mesh - not to heavy to be useful.

Accurate dimensions, taken from existing, previously bought product -using caliper if possible to measure diameters etc. - no guessing or working with internet-photos only.

Carefully created textures based on 360 degrees photo scan and 3d Model is created manually to mainain optimal square polygon structure.
Texture captured this way looks more natural comparing to other techniques. There are no such things as taking off labels to scan them etc - it's always visible and seems unnatural.

There is also one benefit more - I'm trying to make my models work in every light conditions, in case of transparent objects I'm making transparency, bump maps etc. but I'm working as creative designer and I know that sometimes we must put 100 bottles on a shelf - and this is the moment when my show their advantages. You can remove transparency, remove reflections and rendering will go turbo-mode speed but the look of the product models will be still superb with subtelle reflections, blicks and other things captured during 360 degrees photo scan. -these little things that make real-life objects look natural.

Because of simple stack structure:
(spline+lathe+UVW)
it's extremely easy to reduce amount of polygons to your needs.
You can reduce interpolation accuracy of the spline and also number of steps in lathe modifier.

From my experience I can tell that presenting project to the client with his own product od the display/shelf that look crappy can be decisive.
Enjoy and boost your work to pro-level.
