Owner?

Well if you buy a product you own it and no one can take it away from you. It is not completely your you cannot sell it as your own that would be theft. It is the company who created the product that really owns the product not the purchaser or the buyer. You do not have the right in any way to modify the product if you are going to sell it. In my opinion I think that if you are going to modify it for yourself then there is no problem. If you do end up trying to sell it well the best thing to do is to propose this to the company. They will buy it I hope, they won’t be fair if they take that from you. If you buy something legally you don’t have the right to sell it if you don’t have permission to sell the product. That is illegal if you try to make any kind of profit on that product. It is different if you only share the product with others and make nothing out of it. That is one thing that you could do with that product crazy that you really don’t own that product. It seems like you are just are borrowing it even if you did really buy it.
