Today, no-name brands are made in Asia on flimsy and ill-fitting fiberglass trees with nickle plated hardware (that will rust), crooked workmanship, and weak/stiff chemically tanned painted leather that's better off used for coasters or $5 walmart wallets.
I hate to burst your bubble, but you just wasted $300. It "looks" pretty, but it won't last and may very well sore your horse. You also won't be able to sell it for anything once you decide to buy a decent saddle.
I bought my early 1980's Park and Trail saddle by Circle Y for $350. I helped a friend by a Sulphur, OK Billy Cook barrel saddle for her daughter (used but in good shape) for only $325. You can always find a good deal on a quality used saddle if you take your time and are willing to really look.
