great size for one hand spraying [SEP] the sturdiness low rating is due to one of the sprayers not working after just a couple uses it now dumps out the spray in one big drop wasting my product the funnel is useful though i really did not need of them i would rather have functional sprayers to go with my bottles instead i have one bottle that i cannot use and i paid too much for them doubtful the other sprayers will hold up i will not order these again
