Sonic boom is the only brand that works for me, and I hope they never go out of business (considering buying another clock just in case lol bc there’s not another brand like Sonic boom)
Now, one concern that I have for this product is wear and tear, as you’ll put them under your pillow or mattress. Bc it will be damaged, the wire will be frayed, or whatever might happen. It happened to me so many times (including previous brands) and it’s
Another thing to note, which I didn’t realized when I got my sonic boom more than 10 years ago, was that the vibrator disks does have its own warranty (separate from the alarm clocks)
It’s a 5 year warranty from the date of your purchase. Now I don’t usually keep track of things like that, but for this one, I would definitely keep the receipt, that way you don’t have to buy another disk
