Before buying any kind of baby carrier...

I personally haven't used any baby carrier. But if I would buy one, I would certainly buy something like the ergo baby carrier. First, it has a brand name. And I can get to choose different types of carriers. Ergo is into making baby carriers, so they are more concentrated on how to make mothers and baby happy with their product.

But before buying any kind of baby carrier, may it be from a company with a big name on baby products or not, make sure you check the following first:
Is the straps sturdy and heavy duty? Is the strap lock plastic or steel? Plastic or steel lock, is the strap lock sturdy looking? Won't the strap slip on the lock?
Check the cloth material of the carrier. Is the cloth breathable or would it make the baby so uncomfortable because of the heat?
Is the carrier soft for your delicate baby or toddler? Is the cloth smooth, or too course, or too slippery for your baby?
Where will your baby's legs go? Would the legs divider on the carrier makes your baby uncomfortable, or might give him rashes because of the cloth?
Is the carrier too heavy?

Go on, touch the cloth of the carrier... try it on too. Because the carrier is for the comfort of both the mother and the baby.
