I've done a lot of my training with dartford beauty academy. I found them quite good but think it depends on the course. I found that it's great if you get it and don't need anymore help as i did with gels, but acrylics i find a bit harder and there is no after care and they pass everyone it seems, a couple of girls really ruined my nails as we practice on each other....she filed my natural nail so far i still can't touch it and this was last month!! I don't think they are bad but you need tons and tons of practice after and i am always reading on this. I think if you can afford it I would ideally go for 121 training which often isn't much more £ and you can research good companies on here! that way they pay all attention to you and you get the aftercare i think is needed. I did acrylics, man & ped, gels and eyelash ext with them but have now decided to do my spray tanning with a company 121, and i think my other courses will follow the same way and go 121 training!
Sorry if i have gone on a bit - hope it helped?
