What our customers say
★★★★★
Went straight on the tree. The gold edging catches the lights beautifully and it sits upright without drooping like our old one.
★★★★★
First thing every guest picks up. The gold dish is heavier than I expected and it holds my keys and rings perfectly.
★★★★★
The pair looks like something from a gallery shop. Matte finish, no fingerprints, and the stems sit exactly how I wanted.
★★★★★
My daughter played with this for an hour straight, which never happens. Solid wood, smooth edges, no splinters anywhere.
★★★★★
Two sizes was the right call — the small one lives by the stove now. Wipes clean in seconds and no staining so far.
★★★★★
Silent movement, which was the whole reason I bought it. Looks far more expensive than it was.
★★★★★
The glow is soft enough to leave on overnight and the numbers read clearly from across the room.
★★★★★
Mounted under the cabinet in five minutes and it hasn't budged. Tears one-handed exactly like it should.
