What we make of it

This soundbar delivers good audio quality with a built-in subwoofer, making it suitable for those who want an upgraded TV sound without the hassle of multiple components. It's ideal for small to medium-sized rooms and provides a rich sound experience for movies and music. However, it may lack advanced features like Dolby Atmos support, which could disappoint home theater enthusiasts. Also, check compatibility with your TV and ensure it has the connections you need, as it may not work with older models.

Why this is a good deal

It is the lowest price we have recorded

Across 2 sightings of this product, $79 is the lowest we have seen it. The time before this we recorded it at $89.

It is shallower than the typical Tech discount

The median discount across the 151 Tech deals we have live is 44%. This one is 43%.

What you actually keep

$60. A percentage is a ratio and a saving is money — on a cheap item a huge percentage can be worth less than a modest cut on something expensive, so this is the number we would judge it on.

Reasons to think twice

the discount is only a saving if you were going to buy the thing anyway.
