Review: Works very well - This is a simple solution to keep a door open. My front door has a self closing hinge for fire regs. When carrying bags or heavy items it was a nightmare to negotiate. This door stopper works a treat. Easy to install (took 20 minutes) A previous review said the small screws for the hook nose were not strong enough. So far l have not found that to be the case and it works fine. A cost effective simple solution. Highly recommended.
Review: Fermapersiana ottimi soprattutto per cappotto - Al contrario dei classici fermapersiana a scatto realizzati in plastica che con il passare del tempo tendono a spaccarsi per via di acqua, freddo, caldo questi sono realizzati in robusto acciaio verniciato. La molla non è propriamente morbida già dall'inizio e se ferma per svariato tempo o sottoposta alle prime intemperie si irrigidisce ancora di più. Sarà male di spruzzare un po'di grasso spray. L'ho preferiti sempre a quelli a scatto, soprattutto per via della facciata davvero sempre esposta al sole e per via che sulla stessa è stato applicato il cappotto termico.
