Contact for Module PricingWe believe in transparency. Here's what we're working through:
Component availability can be unpredictable, especially for specialized sensors like the SEN66. We've secured initial stock and have backup suppliers, but global chip shortages could cause delays. We're monitoring this closely and will keep backers informed.
This is our first large-scale production run. While we have experience with prototypes, scaling to production quantities may reveal unforeseen challenges. We've built buffer time into our schedule, but delays are possible.
While the core functionality is complete, we're still refining the user interface and adding features based on beta tester feedback. Final software may differ slightly from what's shown, but will maintain all promised functionality.
International shipping can be unpredictable, especially with lithium batteries. We're working with experienced logistics partners, but customs delays or regulations could impact delivery times. We'll do everything possible to minimize delays.
We're pursuing FCC, CE, and other relevant certifications. While we're confident in our design, the certification process could require minor hardware modifications or cause production delays.
Every unit will be tested before shipping, but with complex electronics, some issues may only appear in the field. We're committed to our 6-month replacement warranty and will support our backers with any issues that arise.
We're experienced engineers passionate about air quality monitoring. We've already completed working prototypes and beta testing. While challenges exist, we're committed to transparency, regular communication, and delivering a product we're proud of. Your trust means everything to us.
