Update: The HF3510 is now up to $99, which is a decent deal for that model, but not as good as $90, obviously.
The entry-level Philips HF3500 has been down to $50 for a little while now, but outside of a brief $40 sale, that’s as low as it’s gotten on Amazon. But the higher-end HF3510 just joined the party with a
$90 sale, matching the best deal Amazon’s offered since 2013. Compared to the 3500, the 3510 adds “natural” wake-up sounds, FM radio, more brightness settings, dusk simulation to help you wind down at night, and more.
