Très amusant

J'adore le produit fini. Les instructions auraient pu être un peu plus détaillées dans quelques domaines, mais assez faciles à comprendre et c'est un petit gadget amusant à avoir assis dans le rebord de la fenêtre. J'achèterais encore.

Great fun

Love the finished product. Instructions could have been a little more detailed in a few areas, but easy enough to figure out and this is a fun little gadget to have sitting in the window sill. I'd buy again.
