Before buying, there weren't MANY reviews and the ones that were there didn't really answer a lot of questions I had. So I ordered it and now leaving a review for others who have similar questions before wanting to buy this product. Also, there are some heads ups. It didn't come with instructions, which both the company and Amazon have been made aware. The sizing is completely off- runs VERY SMALL- apparently Amazon is aware of that, too. I don't know why no one has updated the product information on this page, yet, but it caused some issues when I returned the item. Believe it or not, instructions would have helped to clarify. I may have used it incorrectly or didn't place it on me the right way (maybe) but it did not offer much of a difference, either way. I am 5'1 and normally weigh 108 lbs (I'm in my 8th month and at 130 lbs, if that helps you to gauge) I ordered a Medium because of other reviews and I'm glad I did because it fit (any smaller would not have fit) but even that was pretty snug. I'd prefer more room for comfort. So, even at my size, I'd go for a large. That lack of room may have been the cause of my opinion that this item is not comfortable enough to wear as it suggests: You can't wear it while laying or sitting because there's no purpose (since it's helping to carry the weight, when you lay or sit, there's no weight to carry), which eliminates a portion of why to use it. So, you would need to wear it while actually doing things that cause back pain: errands, bending and lifting, walking for awhile, etc. There are a couple problems with this. It does NOT fit discretely under clothes, so unless you plan to wear a tent to the grocery store, it's visible and actually pretty awkward looking. That eliminates another good portion of why I would need to wear it. The remaining purposes are to wear it around the house to do chores that require bending/lifting, which cause pains. I found it to offer mediocre support. It didn't do NOTHING at all but there are so many purposes to the band that were eliminated that it did not make it worth the cost and SLIGHT support I felt while doing chores around the house. I would say that, while wearing it, it offered decent pain relief (not complete but I could tell a difference). However, it wasn't lasting. As soon as I took off the band, my back hurt again...which didn't help for the other reasons to have the band, during which times I could not wear it. I'd say, overall, it's not worth the cost. I don't know if there's anything else available but if you're looking for something to finally relieve that back pain, this is not versatile enough to be the right item. However, if you're looking for spurts of small relief for around the house chores and don't mind the cost of that minor relief, then this would be a good product for you. I should note that I am mostly considering cost-benefit factors and if it were half the price (around $15), this item would definitely be worth it.
