Lifetech inline pump

[Willito]

Does any one own one of these pump or know of any thing (good/bad) about it? I've seen a 1200g/hr (r4600) model going for $50 and was wonder if it worst looking into. I need a pump for a close loop applicating that won't be requiring a high pressure rating. Is it worth it or will I be throw away my money?
