I can't say if this product does what it says on the tin, I'm sure it does, many others have used it with great success but I can did not get the thing to turn to you it takes a body builder to loosen the bolts, me and my mother tried to loosen the fittings together but to no avail, we take them to the machine shop to loosen them , so we don't remove the parts so I can. If necessary, send them back. Overall, it's probably a good device, but I can't say because I don't have enough muscle to undo the damn screws. I'm only complaining because a more informed YouTuber on the subject says this is a clear sign the threading is poorly done and will likely be removed later.
