EIVOI bed shaker vs. Sonic Bomb SBB500SS
Short answer: these two land within a penny of each other — $44.00 for our own bed shaker clock, $44.99 for the Sonic Bomb SBB500SS (list $72.99, at sonicalert.com and diglo.com) — and at that price they buy you two different philosophies, not two versions of the same product. The Sonic Bomb fires a 113 dB siren, a wired 12V "Super Shaker" pad, and flashing lights together, and it's the category's longest-standing name for a reason: if you or someone in the house is profoundly deaf and can't afford a morning where nothing works, that triple-channel redundancy is the safer default. Our clock drops the siren entirely and puts everything into vibration — a wired pad under the pillow or mattress plus a 7.5-inch display — which is the better pick when the person who needs waking hears fine but sleeps through everything, and a 113 dB siren every morning is a problem for whoever else is in the room. Since we make one of these, weigh our side of that sentence accordingly.
Full disclosure: we make the EIVOI bed shaker clock. All Sonic Bomb figures are from sonicalert.com and diglo.com, checked 29 August 2026, and subject to change. Where the Sonic Bomb beats us, we've said so below — and it does, on several rows.

Where the Sonic Bomb wins
Three things, plainly. First, redundancy: siren, shaker, and lights firing together means a failure or a habituation to any one channel still leaves two working, which is the honest argument for it as the default pick for profoundly deaf sleepers or anyone whose mornings genuinely cannot fail. Second, published control specs — the 5-level dimmer, the 1–30 minute snooze window, and the 1–59 minute alarm duration are all stated, where our clock doesn't publish equivalent figures. Third, track record: a 113 dB siren backed by a stated 1-year warranty and review widgets showing 24, 38, and 97 reviews across three different storefronts (sonicalert.com, diglo, Best Buy) — counts each seller displays itself, not independently audited — is a longer paper trail than a newer entrant can match. If your priority is one device that's least likely to leave someone unwoken, that history is worth paying attention to — even though the price is functionally identical to ours.
The battery-backup line deserves a caveat in both directions: Sonic Alert states the SBB500SS keeps its clock settings through a power cut, but doesn't publish what type of battery does that job, so don't assume it's a commonly available cell you can swap yourself.
Where our clock wins
The core case is the one in the short answer: no siren-led design. If the person who needs the alarm hears fine and the problem is depth of sleep rather than deafness, a 113 dB siren is solving a problem that doesn't exist while creating one that does — waking a partner, a roommate, or a baby in the next room every single morning. Strip the siren out and you're left with a 7.5-inch display (larger than a standard alarm clock face, useful for anyone checking the time half-asleep) and a wired pad that does the same physical job as the Sonic Bomb's shaker, without the acoustic side effects.
Two more differences that are easy to overlook because they're not exciting: free shipping with no minimum order, and 100 days from the date of delivery to decide it isn't working for you — a longer and more plainly stated return window than diglo's 30-day policy on the Sonic Bomb. For a product whose whole premise depends on whether vibration wakes your particular body, a longer trial is not a minor perk; it's the only feature that actually de-risks the purchase.
