I've been using Estrid for about 2 years and honestly really like them.
Don't need blades as often as they suggest so just have them shipped every 3rd month and the actual razor itself has lasted reason well.
Love that they're just delivered too so I never run out 
50% off a starter pack with this link if anybody wants it, it makes the razor handle, holder and 2 blades less than £4
