SensMax L3 Wireless Customer Survey Button

The SensMax L3 wireless customer survey button is a compact, battery-powered device for quick customer satisfaction feedback collection. Featuring three clear smiley icons (happy, neutral, sad), it allows visitors to leave instant feedback by pressing a button. The device installs in seconds, either in a plastic question holder stand or directly on a wall or desk, making it an easy way to monitor service quality and customer experience.

How It Works

Each press is recorded and stored in the survey button’s memory. Every 20 minutes, the data is transferred via a SensMax SMX data gateway to the reporting portal or local server. Built-in spam protection ensures reliable statistics by ignoring repeated presses within a short time. Reports include customer satisfaction trends, Net Promoter Score (NPS) calculations, and combined analytics with people counting data for deeper insights.

Installation & Operation

The device runs on standard AA batteries for up to 2 years, with no cabling required. Setup takes minutes: mount the button in its holder or at the desired spot, pair it with a gateway, and start collecting real-world feedback immediately. A built-in backup memory stores up to 25 days of data, ensuring no information is lost if connectivity is interrupted.

Business Impact

Feedback buttons provide a simple way to monitor customer satisfaction in real time. Regular reports highlight service quality trends and help identify weak points. Net Promoter Score (NPS) metrics offer a clear benchmark for improvement and allow direct comparison across branches or service points. Combined with visitor traffic data, the survey system shows how satisfaction levels correlate with customer volume, supporting data-driven decisions in operations and staffing.

Example in Action

A retail chain installed SensMax L3 survey buttons at checkout areas. Customers rated their experience in seconds by pressing a smiley button. Reports revealed that satisfaction dropped during peak hours, correlating with longer waiting times. Based on this insight, additional staff were scheduled during busy periods. Within a month, satisfaction scores rose and checkout efficiency improved, directly boosting customer loyalty.
