Good, but not exactly as described. I ordered the 65mm wheel which is described as having a 4.1 mm axle hole. The hole is actually about 3.1mm. Fortunately, unlike other wheels of a similar design, it is quite easy to drill out the wheels to 4mm without destroying the hub. In a way, this is better because you can drill it out to whatever size you want, but banggood should update their listing accordingly.

The 4 wheels 20mm received do not look like the photo of the web page, the rim is different and the tire is much thicker (the wheel is Piper Cub style, small rim and big tire). The foam is soft, the tire can be removed from the rim. The rim hole has a diameter slightly greater than 2mm, suitable for a 2mm axis. Tyre diameter=20.4mm, tyre width=10.8mm, rim diameter=6.1/8.1mm, rim width=10mm. 1 wheel weighs 0.6gr (rim=0.5gr and tire=0.1gr). The 4 wheels 16mm received do not look like the photo of the web page, the rim is different and the tire is much thicker (the wheel is Piper Cub style, small rim and big tire). The foam is soft, the tire can be removed from the rim. The rim hole has a diameter slightly greater than 2mm, suitable for a 2mm axis. Tyre diameter=16.3mm, tyre width=10.6mm, rim diameter=6.1/8.1mm, rim width=10mm. 1 wheel weighs 0.5gr (rim=0.5gr and tire=less than 0.1gr). The rim has the same dimensions as the 20mm diameter wheel.

Les 4 roues 20mm reçu ne ressemblent pas à la photo de la page Internet, la jante est différente et le pneu est beaucoup plus épais (la roue est du style Piper Cub, petite jante et gros pneu). La mousse est tendre, le pneu peut être enlevé de la jante. Le trou de la jante à un diamètre légèrement supérieur à 2mm, adapté pour un axe de 2mm. Diamètre pneu=20,4mm, largeur pneu=10,8mm, Diamètre jante=6,1/8,1mm, largeur jante=10mm. 1 roue pèse 0,6gr (jante=0,5gr et pneu=0,1gr).

La jante a les mêmes dimensions que la roue de diamètre 20mm.
