I am getting couple of those for my birds and don't know what flavors to choose. I am certainly getting Watermelon as a lot of people said it was their birds' favorite. They also have Grape and KiwiLime.
Which do you think cockatiels would prefer?

They might not care. Birds are thought to have a poor sense of taste, and cockatiels aren't keen on fruit because it's not part of their wild diet.

Obi had something similar... never bothered with it the budgies have it now.... Obi doesn't like fruit much either...

They'd better like it...

They at least sit on the new perches (which is handy -- we need more sitting places with so many birds) and some try to nibble on them.
I have another problem
Ingredients listed on the website didn't look very bad to me :
Ingredients
Calcium Carbonate, Bentonite Clay, Bee Pollen, Potassium Chloride, Dicalcium Phosphate, Sodium Chloride, Sodium Silicoaluminate, Dextrose, Natural Grape, Kiwi/Lime, or Watermelon Flavors, Potassium Iodide, and Sodium Bicarbonate.

But when I receive the perches, I was kinda shocked to read what they composed of:
Calcium Sulfate, Bee pollen, with:
propylene Glycol, acacia gum, FD&C Yellow #5, Xantham Gum,
Sodium Benzoate, FD & C Blue #1, and natural flavors.

Are they safe for my birds to use?
I was fooled by so many positive reviews. Will be contacting Dr Foster and Smith about their very inaccurate description!

There's nothing dangerous there, but they should have put an accurate description on the website.
