Price and rating as shown on Amazon when we collected them. Both change.

The Keepsmile strip is the top entry in this guide, and on price per metre it is the cheapest way here to cover a large room: £14.99 buys 30 metres of tape as two rolls of 15M, a remote, a Bluetooth app with 16 million colours, 64 scene modes and a timer. It is rated 4.4 out of 5 from 25,489 ratings. The listing marks it Not Water Resistant and Indoor, which matches the bedrooms, kitchens, stairs and ceilings it is sold for.

Two things on the listing do not line up with each other. The wattage field reads 17.6 watts across 30 metres of tape — roughly 0.59W per metre — while the voltage field reads 24 volts through a corded power adapter. And the title counts two rolls of 15M, while the Number of Items field on the same page says 1. Everything below comes from the Amazon listing as it stands, not from a test we ran.

What buyers actually say

Quoted from customer reviews on Amazon

“These lights are very good especially with music the only thing they don't tell you in the instructions where you can safely cut them if necessary. UPDATE, after Emailing the company Ive found that they can be cut at the point where there are 4 small metal strips. I cut mine successfully just after this point and they work just great. UPDATE I've had these less than a week now and at first they were great but now most of the options on the app don't work. The scene part does nothing at all and in the Rhythm part only two of the options do anything. It's a shame because they were good. I shall have to take them down and bug some better ones”

“Work amazing the adhesive actually sticks and the durability has proven itself I have knocked it quite a few times however has stayed perfectly in place. The various levels of brightness are also very helpful for different activities so I'd say it's definitely worth the price the app also connects well for the most part but sometimes the app doesn't pick up that the lights are on”
