That one isn't too bad but the Higgins Vita Garden is a bit better because it has less processed foods and is sugar free. The Sunburst has quite a bit od dried fruit, and while that's ok for syrians, dried fruits usually contain chemical preservatives etc (they don't have to declare the ingredients of the dried fruits). It also relies on hay and alfalfa quite highly in the list of ingredients.
The protein is a bit low on both the Sunburst and the Vita Garden at 15% so it would need supplementing and the occasional mealworm is one way to do it. But you could also give some other fresh extras like a bit of chopped hard boiled egg a couple of times a week and the occasional half a walnut. Nuts are good for protein too and they usually LOVE walnuts!
Opi will be fine with the Sunburst and some protein supplement for now, but when you next get some I would get the Higgins Vita Garden instead

And with any hamster food, it's a good idea to freeze it for a week before use, to avoid any buglings hatching out from invisible bug eggs! Don't worry it might not happen and I went a long time with no issues, but once it did happen that was it - I freeze all hamster food for a week now - to kill moth eggs mainly.
Unfortunately all pet foods contain moth eggs apparently. They're not visible to the naked eye and do no harm and they are dormant - until a certain environment is created and they can hatch out then. It needs to be particularly warm for that usually. Freezing the food kills the moth eggs.
How is little Opi doing? Does he like his mealworms?
