Amazon Renewed...Is it worth it?

I'm looking at getting a router and modem from Amazon. They currently have versions of them in their Renewed program which sounds basically like "refurbished". I'm thinking about getting these on effort to save money. Would you trust these? Here is what I'm looking at:

NETGEAR Renewed R7000-100NAR Nighthawk AC1900 Dual Band Wi-Fi Gigabit Router with Open Source Support, Compatible with Amazon Echo/Alexa https://www.amazon.com/dp/B01HW8XSV0/ref=cm_sw_r_sms_apa_i_E8ctEbY5BMM31

NETGEAR Gigabit Cable Modem (32x8) DOCSIS 3.1 | for XFINITY by Comcast, Cox. Compatible with Gig-Speed from Xfinity - CM1000-1AZNAS (Renewed) https://www.amazon.com/dp/B07ND1PQMS/ref=cm_sw_r_sms_apa_i_v9ctEbXHHEH9A

I'd trust them, sure...no different than any other refrub IMO.

only 90 day warranty, so figure value based on that as well

Personally if I get refurbished/renewed I try to go with manufacturer refurbs, but suspect Amazon will do a better job than some small no-name shop that may not have the support or knowledge base to do a proper repair if needed.

I have ordered some stuff from Amazon and have had great luck with all of it
