Flawed, but considering the price, it's pretty decent.
My main problem with this machine is that the provided pins simply don't fit, so I had to improvise with something else. Even then, it's very awkward to remove and replace them during use.
The movement of the weight platform is also a bit rough and uneven, and the headrest could have been better positioned or adjustable. At least the assembly wasn't too bad.
Even with these issues, it's acceptable for how inexpensive it was.
