What to know before buying

Listing details to confirm

The listed dimensions are inconsistent: the details specify 3D x 6W x 3H centimetres, while the feature text says approximately 13 x 6 x 3 cm. The listed shade height of 14 Centimetres also differs from those dimensions. USB is presented as both a power supply and a connection protocol, while cordless operation is also claimed, so the power arrangement is unclear. Confirm the physical size and power setup for the selected listing.

Customer feedback describes the letters as attractive and good quality, with some appreciation for the colour options and adjustable brightness. Size impressions differ, with customers describing them as both larger and smaller than expected. Lighting performance is also mixed, including reports that a light worked well and that one did not work at all. For buyers choosing a small tabletop accent, this feedback makes the unresolved size discrepancy particularly relevant, while the reported performance variation is worth bearing in mind alongside the listing's USB and app-control claims.
