Product not bad, better than some in DIY stores

After hesitation, I keep it. (Small detail finish in the "neck" interior trim finish requiring hygienic precautions in my opinion), see further.
The advantage: a "consistent" cover, and aesthetics.
The downside: gentlemen, to urinate, impossible to raise the seat, (I have not found a model that does so). So leave a paper towel roll to be able to take a small sheet to wipe each passage, a small box of wipes to clean properly, so as to avoid odors, traces, and risk of infection. (I counsel each time).
Another advantage: three height positions. (Small plastic parts at the front, and bar attached at different heights in the rear = front and rear at the same height!).
For now all is well. See time duration.
Pretty happy.
