Hi there! ok cut to the chase, below are my humble opinions!
1) No, u can actually leave it as long as a week but depending on weather and various reasons but i have heard that pple in cold climates can leave it on for a week or even more
2) Good question. In my case, no matter how, i just felt that tape looks a bit unnatural. I would suggest keeping to glue. It feels sticky but i still thought it holds the best...
3) Beware of children! If they pull hard, chances are the glue will un-stick a bit and assuming u are stuck at a party or what, it might cause u to feel uneasy though i dun think anyone would ve noticed any difference!
4) I stay in tropical climate also and to be honest, that was the sole reason why i ditched it. It was unbearable with the glue and stuff and i have to wash everyday. I finally chunked it after 2 weeks and it nvr felt so good. I felt unshackled. Maybe its just me, dun let me put u off. At least give it a go and if u end up not liking it, its at most some financial loss and totally reversible... provided u are not shaving the frontal and crown cos most full systems require u to do that.
5) Tough luck. After my transplant, i was thinking about it but somehow the info i consolidated tells me that the result of the HT might not turn out to be as good. I did not really go into detail as i was just considering.
6) Again, i cant say for everyone but it din work for me. My undercover was blown once i got into the water. Maybe i din wear it properly as i only tried for a very short period of time!
hope the above helps!
