ANKI HAPPIGO 8Pcs 2.2Bar 32PSI Car Tire Pressure Monitor Valve Stem Caps Sensor Indicator 3 Color Eye Alert

Las válvulas de la nada y sin uso perdieron presión y desinflaron más de una llama que estaba en completo alto total por mucho tiempo, pero no solo me pasó en esa bicicleta que no uso sino que también en mi scooter de un día para otro la llanta estaba baja, al llenarla y poner de nuevo la válvula de escuchaba como el aire escapaba por la misma.

Excellent

These little valve caps are a fantastic solution for one of the most annoying 'features' of cars from a certain era: the TPMS light that tells you a tire is low but not which one. Trying these out on my older vehicle has completely eliminated the guesswork. Now, instead of having to check all four tires with a gauge every time the temperature drops and the light comes on, I can just take a quick glance. The simple color-coded system is foolproof; if it's green, you're good to go. It’s a huge time-saver and provides incredible peace of mind, especially for family members who may not be as diligent about checking their tire pressure. I was so impressed that I've found uses for them on more than just my car. They work perfectly on my bicycle tires and are a game-changer for my trailer, where low pressure can be notoriously hard to spot by eye. The real value of these caps was proven recently when one alerted me to a slow leak from a screw I had run over. I caught the issue immediately, long before it could have become a flat or damaged the rim. It’s a simple concept, but it works exactly as described. Receiving a pack of eight gives you enough for two vehicles or plenty of spares, making this an excellent and practical addition to any car, bike, or trailer.

Ich dachte mit den Ventilen meine Luftprüfungen zu minimieren, da Druckverlust ja angezeigt werden soll. Ist aber nicht so; alle 4 Reifen sind seit aufbringen der Ventile grün. Kam mir doch etwas seltsam vor so lange ohne Druckverlust unterwegs zu sein. Halt an der Tanke mal geprüft und es fehlten in einem Reifen gut 1Bar. Alle schnell überprüft und musste bei 3 Reifen Luft auffüllen. Somit bin ich von der Genauigkeit dieser Ventile nicht überzeugt.
