VIVOSUN Durable Waterproof Seedling Heat Mat Warm Hydroponic Heating Pad 1-Pack 3"*20"

.. was eigentlich nicht verwundert. Schlechte Rezensionen schreckten mich zwar ab, aber die gab es bei JEDER Heizmatte. Wichtig ist - meiner Meinung nach -, dass die Matte nicht zu sehr beansprucht wird, also nicht knicken, zu sehr biegen, was heißes draufstellen .. oder was weiß ich. Wir haben ein altes Kuchenblech draufgestellt: das verteilt die Wärme gut, schützt zusätzlich vor zuviel Wasser und hat kein Problem mit Kratzern, Schlägen, usw. Die Heizmatte zum Vorziehen von Tomaten oder Chilis bringt seine Temperatur gut hin. Nach 14 Tagen sehe ich natürlich noch keine Ergebnisse .. abwarten!

Works well temp controller is the bomb,had other brand no temp controller and it got very hot and melted ,caution do not Sandwich any heat mat

Não esquenta no meio. Dividindo o tapete retângulo em 3 partes, a do meio não esquenta, apenas as outras duas. E o calor é bem discreto.

It seems well made and does everything it says on the tin. Temperature maintains its setting and goes up plenty high enough. It does not get a 5 star as I cant yet say it continues to perform for season 2 and beyond

Temperature gauge is great, shows current temp and temp to heat up to. Gets warm when it works. UNFORTUNATELY: the mat only stays on for 30 seconds before turning off. Plugged it into several different outlets just in case it was a power fluctuation. Even plugged it into surge protection to ensure steady power source. Still timed off after 30 seconds. Since my intention is to keep my small animal warm, especially during the Canadian Winter Nights, this is not ideal. Would be great if it worked longer than 30 seconds at a time. Do not recommend if you rely on this as sole heat source and constant running for the safety of animals, as it will not give them adequate heat supply.
