The pump mechanism is bad quality and quite faulty. I was surprised as this is is something that cannot go wrong but did :( The pump from day one worked sporadically. Then the whole mechanism came off one day after a week of usage. I reassembled it but it doesn't work at any more. Everything else is ok, but if the bottle cannot spray water or soap water it is very much useless.
Good for spraying disinfectants, sanitizers and other liquid things.. Material is moderately thick.. Not very sturdy.. One of my spraying bottle was not working 2 days after delivery, but after some tweak it's now working..
