Back Stretcher for Lower Back Pain Relief with Magnet, 3 Level Adjustable Back Cracker | Back Massager | Back Pain Relief | Back Cracking Device | Spinal Decompression | Spine Corrrector

This thing is great. I had low expectations because I've bought crappy, cheap back relief before and wasted my money. This was TOTALLY not that. It is cheap. It's so cheap that I feel like I got away with something. I have used this nearly every day for a couple months now, and turned my partner and my buddy onto it. My back has been pretty crunched from lack of activity this last year (pandemic), and I found myself wanting to lay on the floor all the time to try and find relief. I craved some support and bend, so I got this thing, and now my posture is better, my back pain is gone, and I haven't even started using the third setting yet! It takes a couple days to get used to, it hurts at first, but once you've gotten yourself use to it, sometimes I just go lay on the thing because its comfy to do so. The ONLY thing that I wish was a little different was I wish the plastic was a bit harder. It can sometimes give way underneath you as you are getting up off of it (and I'm not a big dude). But it's fine, just don't count on it to support you %100 while you're getting up.Buy it. It's super cheap, and it has actually become one of my most used things in my house--probably only beat out by my computer and cast iron pan.

Plastic seems durable enough. I've tried all 3 settings and the lowest works best for me. The magnets don't seem to do anything, they could eliminate those and reduce the price without losing any functionality. Other design flaw is there should be detents to keep the upper part from sliding sideways - not really a problem during use, but be careful how you pick it up to move it. It does stretch out the back and I can feel the pop when laying on this if my spine is out of alignment (which I was never able to feel from the inversion table I had prior).

I have used this for a little over a month and really all back pain is gone. Yes lower back too....I feel like I am 21 again. It works great but the instructions were lacking so let me tell you what I do. You assemble it and get the curve set up on however aggressive(or lowest) you want but I use the least aggressive. I put the widest side next to but and the narrow up on towards the middle of the shoulder blades. I laid on it the first time for 1 minute,,,then roll off and lay flat on my stomach a minute. I did this for three straight days. The results at that time was well strange,,it felt loose and yet their was some phantom pain I guess associated with it...you know when you expect pain. I worked up to 3 minutes of stretching twice a week and still roll off and let rest for a minute before getting up. No pain...hope this helps.

Just ok. It will definitely stretch your back however the rubber strip along the center is rather flimsy not sure that it adds much value. Same with the magnetic pressure points. Other than a stretch of my back I did not feel any significant pain relief.The value I see in this product is increased flexibility. Sometimes increasing flexibility will naturally support pain relief however the acupuncture points on this do not seem to target any pressure points specifically. The same pain relief can be achieved through simple PT exercises with no cost. This device is very useful for gradually expanding your back stretching if working towards strength and flexibility for yoga or general wellness.If you are looking for this as a seating/posture option, look elsewhere. The strap provided to attach to a chair for better posture is not attached and there are no clear instructions or slot points to feed through. In other words it’s rather useless you just feed through the wide open points on either end. In this case without fitted slots there is a lot of room for slip to either side resulting in an uneven and uncomfortable posture positioning. Without a fitted slot to hold this securely in place the gap in the back of an office chair means it’s useless. In a fabric chair or recliner I would be concerned this hard plastic could catch on the upholstery and tear it. I wouldn’t even consider for leather furniture.I had hoped to use this for my office chair as a posture corrector but the strap is useless. Too short and no proper fittings to hold securely. I have a Steelcase standard sized office chair and this strap is not long enough to stabilize properly if assembled vertically or horizontally along the back of the chair. I also have a Herman Miller Aeron which has a wider back and this would never fit around. Thankfully the HM has its own adjustable lumbar support it is only provided here as an example for sizing purposes.I am small 120lb so do not have the weight limit concerns however I would be cautious letting someone over 200lb use this device because it is made of hard plastic and held in place by matching hard plastic slots. I could see this giving way or failing to hold up over time, posing more of a danger than a benefit to larger folks.Overall this is just ok. I had hoped to use with my office chair to improve posture and that was a no go. The other reason I purchased was for stretching. It served this purpose well enough. This device helps with attaining more flexibility in these times of sitting at home and I am using as part of my warmup workout routine. The price was right but the numerous benefits and uses in the product description are too good to be true.
