Amvona is no name stuff that someone decided to slap a name on...literally. The stuff smells of stuff that is mass produced by companies paying their labor crap per day with no benefits and probably unsafe factory conditions, then sold in bulk to companies like "Amvona", and finally labeled as if they were actually a company that makes photo equipment, when in fact, they are just a reseller.
I was given a bag years ago. It is OK. It broke almost immediately, but I tied the strap. It works. In fact, it is one of my normally circulated camera bags, so I use it quite a bit. I would not actually pay for it, however, and I would certainly not even try something like a tripod. There is a big difference between a bag and a tripod. Quality matters a lot more with the latter.
These are general statements. There might be a decent product here or there, but in general, I would say a used tripod from a reputable company is a better choice when it comes to getting a deal.
