Here is the Etsy shop that I purchased them from:

I bought the trial pack so I could see all three Syrian mixes and I have review all three dwarf mixes HERE.
HamsterLife has three mixes. Basic, Feast, and Muesli. What I like about these mixes is that they look like they are all unique mixes, not just a small tweak here or there. The packaging was good and the ingredients smelled fresh.

The Basic mix was very nice, I think this is a great mix if you want a mix that you can mix and match, add some of your own ingredients to, etc or just add some variety to your own mix. It does not include any animal source of protein so you will probably need to add one. I think it's nice to have a mix without protein since as we know hamsters can be very picky about chicken vs mealworms vs crickets, etc. You'll be able to add your own.
Ingredients:
Rye, barley, wheat, spelt, vetches, unripe spelt, dari red, paddy rice, kamut, dari white, wheat flakes, barley flakes, oat flakes, buckwheat, oat kernels, safflower seeds, pumpkin seeds, sunflower seeds peeled, milk thistle seed, hemp seed, linseed, rosehip seeds, exporter of Spinach Seeds, Red Lentils, Brown Lentils, Yellow Peas, Pea Flakes, Broad Bean Flakes

The Feast mix has a lot of variety, added mealworms, nice variety of herbs and dried veggies. With some unique seeds, I don't see often in hamster mixes. Overall, I think if I were going to buy one of the mixes, I would likely choose this one. This mix seems like a good general mix for an adult Syrian (6+ months).
Ingredients:
rolled oats, spelt, oat kernels, rye, barley, mung beans, corn popped broken, mealworms, pointed seeds, red peppers, diced carrots, parsnip root, peeled sunflower seeds, shelled peanuts, gammarus, hemp seed, niger seed, safflower seed, linseed, milk thistle seed, carrot seeds, Sesame seeds, sweet fennel seeds, turnip rape, perilla, brown, dari red, millet Japan, millet yellow, buckwheat, spinach seeds, puffed rice, calendula blossoms without calyx, hibiscus blossoms, rose petals, chamomile blossoms, sunflower leaves, daisies, mallow blossoms blue, peppermint leaves, dandelion herb cut, ribwort cut

The Muesli mix also a lot of variety with more protein added like dried grasshoppers and silkworms (<6 months hamsters need more protein) and less herbs. I don't mind the corn in the mix because it's from the Netherlands and they have less GMOs than the US. It does have raisins, but it's for Syrians so that isn't an issue to get an occasional raisin.
Ingredients:
Rolled oats, rye, barley, oat kernels, wheat, spelt, pea flakes, corn, Milo, Dari, sunflower seeds, peanuts, carrots, peppers, mealworms, zucchini, beetroot, parsnip, safflower, raisins, pumpkin seeds, paddy rice, broccoli, Grasshopper, Silkworm, Cabbage Seed, Grass Seed, Spinach Seed, Radish Seed, Carrot Seed, Puffed Rice, Marigold Flower, Rapeseed, Sesame Seed, Dandelion Root, Green Oat, Cornflower, Peppermint, Dandelion Herb, Chamomile

Overall, I liked all three of these mixes. I felt like they were carefully planned and not just the same mix with a few different ingredients. They were all very distinct and think these would be a good option for anyone looking for a Syrian hamster mix. Curious to know if anyone else has tried these mixes. My hamsters enjoyed them!
