We opted for this beautiful cage express it big enough for our budgies ist.Der construction gind very fast man must open the cage and the roof very überspannen.Ging fix without tools or similar to benutzen.Ich find that very well with the wells Man no longer has to reach into the cage to clean it or to refill simply folds the roof high and you can directly entnehmen.Also for the money is the cage a bargain I can only recommend.
