I bought myself one for Christmas, life changing!

this is the one I got as a gift at Christmas. so I haven't had it a very long but so far I haven't had any issues with it! I think this brand also makes an XL size too.
This is my number 1. Can’t recommend it enough: https://www.amazon.com/dp/B08QZK68BY/ref=cm_sw_r_sms_apip_iyBlDPAaZ2WRK My fave thing about it is the wide range of timer settings. I always worry about getting burnt in those times that I can’t sleep without the help and being able to set it to 30 min reassures me that it will turn off soon after I’ve fallen asleep.
