Hi I need some advice and hope u can all help... im a mobile tech and have just realised with my new insurance policy I need to have full product and equipment brand for full coverage. Basically because I use HARMONY GELISH but use a gellux lamp ( because I had started out with gellux brands to begin with the upgraded to gelish)I will NOT be covered for a claim if made with this product.... so I need to buy gelish lamp (was going to at some point anyway) but cannot decide wether to go for g6 or g18 as the more £ I save the more I can put bk into product but would like every1s opinion on the matter or comparisons if possible.... many thanks leane xxx
