Review on EasyDrain 510 Expandable Flexible P Trap by Devon Dober

I have a Dodge van and have done some plumbing myself. I had a different type of drain that started leaking a while ago. I purchased this replacement hose and installed it myself (I'm a 67 year old female). At first I couldn't screw this thing to the bottom of the sink without twisting it at an angle (which is why I gave it 4 passes per install). I kept working on it until it just turned. I only used my hands as recommended. It leaked a bit at first, but then I tightened it a bit and everything is fine. I don't have a lot of faith that plastic will last forever, but I don't think there will be any problems for the next few years.
