I haven't tried that one but, to be honest, with the depth set appropriately, I find lancing painless.
I use the ACCU-Chek FastClix which, being a little more substantial than most lancers is more stable.
I have used it for years, first one cost me £140 (included import tax!) from US. Now you can buy from Amazon for around £50.
Do it properly and no pain or marks, in fact I tend to use the same finger and area, no marks.
Designed for use by children too. Can look and sound intimating because the way it works, is it forms a vacuum, pulls the skin up away from nerve endings as the needle goes in, all in a second.
Like most of us, finger pricking can be painful or cause discomfort, more so than injecting insulin.
Genteel uses vacuum and depth control to retrieve the perfect drop of test blood. Perfect for Type 1, Type 2, pre-diabetes and keto. 120-day money back guarantee. 1-year warranty. Free US shipping. $10 local EU shipping.

By the way, even on Genteel site it has images of taking blood on the finger tip? Why? This is where nerve endings are, hence pain. Also nurses are trained to use on the side of your finger. Not to save pain but to prevent numbness, important if you need to read brail.
