Very good recommend
Exact same as on website but cheaper and free next day delivery can’t go wrong came in exact same package the cheaper and quicker. Value for money, fast delivery and works well. So small this is the second one we’ve lost! Hopefully won’t have to order again… but absolutely no issues with product
