I had no luck with this. If you happened to borrow it from a friend and it worked fine for you, I would take it. I tried the RFI but it seems like the liquid just goes to the bottom instead of through the bleed device. I don't know if it helped a little. I then went to try to pump but the bottle cap got stuck and I ended up breaking the tabs and eventually the cap itself. I'm sure a cheaper option would have done the same. The instructions are a little vague in some places, but are mostly detailed. The DVD didn't explain anything to me. Those were the exact same videos I kind of stumbled upon while on YouTube. It wouldn't be fair of me to say it's worth buying or not just because of my luck, I'm really just ranting about it. But if you had the chance to try before you buy, I would choose that option.
