Obviously Philips has changed the product positively.
The mouthpieces are now ribbed as well as the tradition of the latest bottle.
In addition, the set comes with two equally long straws. These fit for large bottles and have to be shortened for the small bottles. On the back of the package can be found for this purpose a template.
The negative recessions with respect to two different lengths straws thus seem to be no longer justified.
Whether the dealer at Amazon.com I can not say deliver the new version of course.
