SodaStream 60 litre Gas Cylinder 5 "New and Exchange" Mr Zeid 03 October 2019 Lakeland are the best price for both new and exchange cylinders. Take your empty to the checkout and they'll exchange it, the current exchange cost (9/2019) being £11.99. I've been using a Sodastream the latest type for a couple of years and it's great, saving at least 500 plastic bottles. If you like fizz, buy one. The syrups are good but expensive thanks to the Jamie B***dy Oliver sugar tax. Plenty of very good syrup recipes available and Lakeland currently have a very good deal on the original cola syrup. Anyone who buys bottled fizzy water needs their bumps felt.
