So, for decades we all had the standard horizontal TP holder.....speaking for myself at least....in any case, I'm kind of sort of remodeling my house and decided to do the easy stuff 1st...this was one of those. Being European, I am a Contemporary style person anyway, so this is not a change for me so much as for any "American " visitor whom has to visit the commode...they all look at me like I have 13 heads after their restroom visit.. sometimes I hear them...OH MYYYYY.. lol. .really funny to hear, bc I know what it's about. Anyways, installation was a snap for me...took me about 10 minutes, and I am by no means a pro...far from it, is more like it. So if you're not a person whom detests change, give it a try...and after a while you WILL ask yourself...this is so much more efficient, how come I didn't get this sooner ?
