I’m nearly 9 months into a Suri sub and I love it. New heads every 6 months and the handset itself still lasts about 40 days between charges - and USB-C!
Elegant simplicity which just works. Highly recommended.
Not sure if a referral will still work though as it has been a while… (Referral Wiki: Post/Find Here) - probably the same, or less, as the direct Suri website discounts.
