Must buy for summer
Color: Blue, Size: 7x7 FT (1～3 person), Color: Blue, Size: 7x7 FT (1～3 person)
Lightweight, compact, and super easy to pack. Sand shakes right off and it dries quickly, which is perfect for the beach.

This picnic blanket is great! Portable, comfy, durable and easy to put back in its sleeve. Comes with stakes and a carry strap. Would buy again. I got the big size and it’s perfect.

Working well for my home physical therapy follow-up needs
Color: Assorted
These bands work well for me to continue my physical therapy regimen at home. I have only owned them for a few weeks but the quality seems to be good for my usage. Just keep in mind I am using these for PT, not for any advanced or lofty strengthening goals.

Good starter resistance bands, nice design and fair quality
Color: Coffee
I recently started working out and spent quite some time choosing resistance bands. I decided to go with this set mainly because it has a huge number of reviews and is very popular, which felt like a safe option for a beginner.
Overall, I think this is a good value-for-money product. The bands look nice, and I really like the color palette — the coffee/milky tones look stylish and different from the usual bright gym colors.
I use them regularly, and they work fine for my workouts. One thing worth mentioning is that if you use them directly on bare skin, they can roll a bit. However, when wearing leggings, they stay in place and feel comfortable.
At this stage, I’m satisfied with them. In the future, as I train more, I’ll probably upgrade to a higher-end set, but for starting out, these bands do the job well. I’d rate them 4 out of 5.
