Actually I bought dr.aquaguard magna uv and it was told that, I’ll be receiving a provoke watch but until now I haven’t received anything. when I followed up for that. it was WORST exp in my life. nearly 3 hrs 7 ppl I spoke with. But no use. it’s abt d watch. it’s abt d poor service and response. they are bloody cheaters. and that model magna uv is not at all worth for that money. it’s just a plastic container. very less weight. So plz don’t go for this product blindly. and ours is a cavery water. And the water is also not that tasty. when u want to purchase they are like ur neighbors . when u want a service, they are like a third person. and u ll go mad by calling each helpline numbers.
