Ok, so we got this product along with a few others (yet to try !). This certainly took us back a few years lol, very strong ! The only thing I would say is the actual smell of the liquid stinks to high heaven lmao we have a teenager and needless to say she was asking what the smell was in our room (awkward !)….we told her it was my wife’s new nail varnish !……she thankfully accepted our excuse ! Unlike the other non pentyl products this one was much harder to clear the air. But ! good product !
