Die anzahl stimmte und alle sind einwandfrei geliefert worden allerdings musste ich einen monat warten bis sie ankamen. Ich finde den preis echt super dafr lohnt sich das warten. Mal sehen wie lange sie halten.

Great Must-Have Safety Item.

They all work perfectly and passed the suck and blow test. these are the diaphragm type which is more dependable than the ball type but you may have to turn your pump up because they do restrict the airflow just a bit. Best deal online and they arrived the next day!
