I don't normally write reviews, but this time i thought i should to help fellow people like myself, who spend weeks looking for an item before buying.Firstly, i ordered the Vevor 1000g grinder. I ordered it last Tuesday and fully tracking information came available the next day. Today is 1 week later and it was delivered to my door in a cardboard box, nicely packaged inside with polystyrene. Anyway, i spent the first 10 minutes trying to open the cover. It needed a firm opening anti clockwise. I put in a few hundred grams of full coriander seeds. I let it grind for about 20 seconds and oh my!!! Beautifully grounded. I decided to try the really thick, different textured, full biryaani masala. I put in a good few hundred grams and put the lid on and let it grind for about 20 to 25 seconds. I was not disappointed at all. Why oh why did i wait so long to order this heavy beauty!?!?! I've spent my life trying out coffee grinders for my spices and they take forever as the machines are small and get overly hot very quickly. This a monster of a machine and if you want something to grind your spices like me, then look no further. You'll not be disappointed. Make sure you screw the lid on tight so none of the ground spices leak out from the sides. It's bloody marvellous is this machine. ?
