The quality of it is mediocre to bad.
Taking out the old one, I realized that its weight compared to the new one was one third. "Very lightweight construction, with narrow passages, which is why there is a lot of noise during use.
If the toilet is close to the bathroom, it is prohibitive. The price is good enough as long as it lasts at least. I have had it for about a week.

I write the review having only tried the phone. The phone was connected to a different battery and when I opened it, it broke in a few seconds and started losing from everywhere. I give it three stars because the price is very low and it is worth someone changing the phone!
