Finally sleeping without anxiety
I used to lie awake listening for sounds at 2am. Stuck TremShield on my bedroom window and stopped worrying. It just works, no app, no setup drama. First deep sleep I've had in months.
The only alarm that works when you rent
My landlord won't allow drilling. TremShield peeled on in under a minute, left zero marks, and comes with me when I move. First time I've actually felt secure in an apartment.
Cancelled my $40/month subscription for this little thing
I paid another popular alarm $40 a month for two years and still had outages. TremShield was $79 for four of them. No contract, no renewal, no app. It was a no-brainer.
No more 3AM false alarms
Every cheap alarm I owned went off too easily. The sensitivity dial on TremShield lets me fine-tune it to my exact environment. It hasn't false-triggered once since I set it up, and it IS loud. Trust me.
