Excerpts from the lifetime warranty policy. The Original Purchase Warranty does not cover consumable components which include: the rain funnel, rain debris screen, wind cups, wind vane, and temperature-humidity sensor module.
Any product which, under normal use and service and after examination by us, fails to meet the Original Purchaser Warranty will, at our sole option, be repaired or replaced by us. Although, as explained below, in some cases a refund will be provided. Transportation costs and charges for returned goods shall be paid for by the original purchaser. We hereby disclaim all responsibility for such transportation costs and charges. The Original Purchaser Warranty does not cover, and we will not repair or replace products which have received normal wear and tear not affecting the functionality of the product, or that have been damaged (including by acts of nature), tampered, abused, improperly installed, or repaired or altered by anyone other than our authorized representatives.
The remedy under the Original Purchaser Warranty is limited to repair or replacement of the defective item(s). If we determine that repair or replacement is not feasible, we may, at our option, refund the amount of the original purchase price.

https://www.acurite.com/pages/warranty-return-policies#LTThe caveats are very similar to other warranties. You will need to send it back for repair so you will be offline for a while. If you only have a 1 year warranty you can fix it yourself after it expires. In this case, with a lifetime warranty you must send it back for repair with the exception of the consumables for the "lifetime" of the unit. IMHO, not for the weather hobbyist that likes to tinker but designed for the weather curious. It has a niche market.
