Awful.
Color: Black, Size: 22"- 4 Panel
Easiest one star review ever. I'm writing this with bloody fingers from assembling this. Multiple poles were bent, none of the pole connectors worked, the hex wrench broke in my hand, the screws didn't really go into the holes provided (I had to get a friend with a press drill to widen the holes to make it work), there are sharp edges on the poles where there is a seam, and doesn't look that great once assembled. Easy do not buy, the only reason I didn't return is because it would have been tough to disassemble the half I got through in the first 5 hours of building (mostly spent fixing the product delivered)

GET A VARIETY SET TO DECIDE WHICH FAVS TO BUY NEXT TIME. YOU’LL LIKELY WANT MORE FRESH OLIVES
Flavor Name: Green & Kalamata, Size: 4 Ounce (Pack of 5)
I did learn of these on Shark Tank and was glad I could try them through Amazon. (I discovered the lemon garlic variety was the one I enjoyed most, so I reordered just those next time.) These are fresh-tasting and hard to stop snacking at one 4-olive serving. If I had guests over, it’s something others would also enjoy. Nice that they come in zipper pack to keep them fresh.

Amazing ‘Go-to’ snack + !
Flavor Name: Kalamata, Size: 4 Ounce (Pack of 6)
First of all, the olives taste great. I’ve tried some other olive ‘snack’ brands in the past and Freestyle is completely next level in quality, texture and flavor!
Secondly, we have zero motivation to buy olives in the jar or at the Whole Foods counter now since these packs work for any application and never seem to get LOST in the back of the fridge. Great branding btw!
2 of our three kids (age 10 and 5) have taken notice and are now a fan of the ‘lemon garlic’. The 10 yr old was initially skeptical after reading the flavor 😂, but after trying them with me was totally down. My wife and I love all the flavors because we use them for different applications - Lemon Garlic and Spicy for snacking (obviously) and the Kalamata for recipes/cooking. My wife is Greek and loves that she now has a healthier alternative always on hand - has even inspired more Greek dishes!
Way to go and looking forward to more great Freestyle Snacks!

Delicious and satisfying. Put more in
Flavor Name: Original, Lemon Garlic, Hot & Spicy, Size: 4 Ounce (Pack of 3)
Delicious. A bit over priced. Wish there were more in the package as I feel like I'm paying for packaging.
