Usually you want to have a product portfolio as small and clearly defined as possible to be well positioned according to marketing laws.
When a potential customer sees too many similar products it get stuck and may easily resolve his dilemma by looking elsewhere.
As is often the case, Apple has been for decades the best lead to follow in this regard, they had the internal rule to always have all the lineup exposed on a single “apple store” table, what couldn’t fit was out. Now, you may have doubt about the quality of Apple offer, but no sane person will doubt their marketing skills.
So, no, the Topping offer is a true disaster from that point of view. Fortunately you can’t go wrong whit Topping products in terms of quality.
