Eternal 5 I'm usually very skeptic about chinese brands because of bad experiences, but this time this product exceeded my expectations!. The construction quality, the fabric, the design, it's just great. I bought it because I'm not a fan of the Ergobaby 360 we have, mainly because I'm big and it's not so easy or fast to use, also because my daughter is bigger than the most average babies, she is not so comfortable in the Ergobaby, but with this Babybear things are better for her now, she is comfortable and she can move freely and I don't waste time accommodating her!.There's no back pain using it, but I'm muscular so I'm not sure if this will be the case for everyone. Let's see how this Babybear works wearing it in time, how durable is, for now I'm very happy with it!.
