I have previously only known Clearblue. Because you need a tester where the test strips are reingesteckt. Is totally unnecessary. This product is very simple, but works well. The handling is very easy. Just the tip of the test in the urine hold until the test is fully drawn (the field where the result is displayed fills blue), then lie down and wait 5 minutes. When a test strip is negative, in two takes your ovulation in the next 30-60 Stundn instead. Yet it did not work with me, but probiers also only at the second cycle. So I think it's really very inexpensive compared to other tests!
