Use of article in front of product names

In English, a definite article is not typically used in front of company names, except if you want to refer to some particular building (e.g. I went to the McDonald's around the corner).

However, does the same thing hold for product names? For example, which of the following sentences would work better?

1. Logitech's new S30 is an improved version of the S29.


2. Logitech's new S30 is an improved version of S29.

The former sounds much better to me, but that may be because we throw around a lot of definite articles in my native language :)
