Good product, slightly pricey

It does exactly what it is supposed to do. The price is a bit higher than generic alternatives, but for safety equipment, I prefer sticking with the original manufacturer.

Fast shipping and great quality

Arrived quickly and well-packaged. The relay clicks solidly and the safety interlocks on our bounce house system are functioning correctly again.

Essential for compliance

We manage a fleet of inflatables and need to meet strict safety standards. This NST-3.2 unit ensures we remain compliant with current regulations. Highly recommended.

Genuine DUELCO part, works perfectly

Needed a replacement for our old inflatable attraction control panel. This is the real deal from Denmark, not a cheap clone. Installation was straightforward on the DIN rail.

Solid build quality

The housing feels very robust and the terminal connections are secure. Took off one star only because the manual was entirely in Danish, though the wiring diagram is universal.
