Yes, I'd recommend that one! My lashes definitely got longer with it, quite fast as well, I think I noticed it about two or three weeks after I started using it and I only used it in the evenings. I can't say that the lashes got thicker though or that there were more of them.
I never tried any of the UKLash serums, so I can't say how it compares.

Another empty:
DermaSel Hyaluronic Booster spray. One of those thermal water sprays with a bit of hyaluronic acid mixed in. Really like it , I used it daily in the morning to mist my face before applying serum. Would buy again, but after another spray-type thing to use up.
Forgot to mention that I also used up Reviderm Anti-Aging mask. Amazing Stuff. Expensive, but very worth it, it contains cinnamon, makes you go bright red for a few minutes but then the face is really, really plump. Probably can't use it anymore or only carefully because of suspected rosacea
