I have used 4QD PRO-160 controller for my battery-powered 7 1/4" gauge locomotive for some years now, and it works extremely well. Delivery was quick (I live in Europe), and the company responded very quickly to some queries I had on installation (totally my fault doubtless due to my incompetence). I found 4QD to be a supplier of both outstanding equipment, and after-sales service.Posted on GoogleTrustindex verifies that the original source of the review is Google.

Steve at 4QD has continually assisted with the success of my race team. We have worked closely with Steve on a number of speed controllers which resulted in us becoming world champions in our field in 2018 and on the podium for the 2019, 20 and 21 season. We were also world champions during the 2024 season in the senior category also.

Hier kaufe ich alles, was ich für meine 5 Zoll und 7 1/4 Zoll Gartenbahnen zur Steuerung benötige. Die Produkte sind von hoher Qualität und ich hatte bisher noch keinen einzigen Ausfall. 👍 Der Support unterstützt bei allen Fragen (und ist auch nicht böse, wenn man mal was im Handbuch überlesen hat 🫣). Jederzeit zu empfehlen.Posted on GoogleTrustindex verifies that the original source of the review is Google.
