I'm interested in understanding the effective range of the product you offer. It's essential for us to know how far this product can perform efficiently under optimal conditions. Could you provide me with the specific distance or area coverage it can achieve? Additionally, if there are any factors that might affect this range, such as environmental conditions or using different configurations, please include that info as well. This will help us make a more informed decision regarding our procurement needs. Thank you!
