I love everything in my box! I was so happy when I saw my new shirt, “Fitness Goal: Pet more dogs.” I love everything else too! The shirt was just my favorite-est! Yay! I have worn the wags and weights sunglasses every day since getting my box. Super excited for my next box!

This months box was very disappointing and gimmick-y. Seriously one brand in a whole box? I'm glad they wanted to sponsor a box, but next time offer that as a separate thing not as the monthly subscription. It was so upsetting opening up this box, I got rid of everything in it. I bought this box because the pics of the gear you all have had in the past were exciting and varied in brand and equipment. If I keep getting boxes like the January 2018 box I'll cancel my subscription. You must be advertising old pics.

A must

The customer service is really bad. My mother purchased the $50 box for me for Christmas. In the box, I had two repeated shirts that I had already received in other boxes. I contacted Gainz at least five times over the past six months, and they never responded. I felt so guilty when my mom was all excited about the gift, and then she saw I had already received the bulk of the items.

Saw the discount code and caption about helping Vets, figured a double win. Got my first box about 2 weeks ago, really impressed. Going to buy a few boxes for x-mas gifts for friends! Can't wait for next month!

love it!

My favorite day on the month is when gain[z]box is sitting on my front porch. All my box mates are jealous when I bring in my box box full of crossfit awesomeness! Everything in the box is quality and worth way more than what I pay per month. This is not just a box of samples.

Seems great so far I’ve only received one so maybe after a few more I’ll give another review, but for now doesn’t seem to be a waste of money and it’s nice having random things sent to the house.

Fantastic box
