I can say this from personal experience (ON ME!) that the hock wraps really work well on human knee pain! 

I've had much better luck with PHT than BOT. BOT made my horse worse after it was removed, I had to saddle and warm up & run within about 20 minutes of taking the sheet off. I don't like heat, heat is bad for injuries and my chiros (human and horse) all say heat creates patients. I sold all mine and got PHT. My horse feels a heck of a lot better after wearing the sheet & hood & it lasts. I don't have anything for my horses that I don't test on myself. I took one of my clean MagnaCU sheets and covered up at a barrel race because I had a migraine. Within an hour I felt like Jello, I was so relaxed. So we tried something, we thought well maybe it was because I knew it was there. So my friend took one of my wonder wraps one day and stuck it on my chair behind my head when I leaned forward. An hour later I wondered why I felt so relaxed and when I got up I realized it was from the wrap. When I have a tension headache I wrap a bell boot around my neck and it goes away pretty quickly. I don't have to take drugs. I fell on the ice a couple weeks ago and wrapped myself in a sheet on the couch & felt so much better. Whenever I put it on my horses fall asleep and when I take it off & ride they can long trot like nobodsy business and are so flexible. So for me, thats enough. I never felt any of that with BOT so I'll stay with PHT. The only thing I don't use is the quick wraps I have because they don't fit my one horse right, he's got an enormous fetlock so you can't get a good fit with them. I have a hard time with sport boots too as his fetlock needs an XL but his cannon needs a M. I usually use DiO on the legs anyway, so I'll keep with that 

I prefer the PHT blanket over the BOT..  I actually notice a difference in performance when I put it on.  Now I do not let my horses live in my PHT.  They get it in the trailer or the morning I run. I pull it off around 2 hourse before I run, which is the routine that works the best for me.

I feel the copper wraps work the best on legs for hauling.  I think the PHT is great for a leg injury, but pulls too much blood to the legs for normal use (JMO).  The BOTs only get put on in the winter when we are headed home and I feel too lazy to wrap the copper ones I have.

I had both.  Sold BOT which hubby told me to keep not eating anything but I wasnt using and I got everything like the neck hocks blanket.  i have PHT debated bout selling that too.  I dont blanket my horses at all I'm in Okla. So not in blizzards.  i used to blanket til one day it was snowing and so cold so I blanket before work by 1-2 in afternoon it was super warm! around 60 and I was stuck at work with no one to take blanket off  one horse tore out of hers the other was sweating! alot and she got sick right after that so thats why i dont blanket.  Anyways my horse never gets cold but we have had so much rain and our ground is saturated.  My horse I believed colic (when he does he lays around) and he laid on ground most day (I was gone my mom said she thought nothing wrong) So when I got home that evening he was shaking so bad and temp 94 and I had no blanket!  I wished that I had my BOT! and all I had was magnet so I threw that on hoping that it would circulate blood and in 15-20 mins he quit shanking and I did give him banamine and went to friends house and got a blanket.  So guress what I bought a regular blanket to have on hand!  The trick that I been told is you gotta use it everyday  but as far as magnets go I dont think you need hock neck stifle and whatever else I think blanket is plenty just bc magnets supposed to circulate the blood.  I can put a wrist magnet braclet and I can tell difference in knee.  jmo

I used my pht quick wraps on my arm after I broke it and got the cast off. I’d put it on before I went to sleep and could tell a huge difference between when I did it and when I didn’t. When I didn’t, my wrist would be so stiff for hours after waking up. When I used it, my wrist was almost normal. 

I have both but use the PHT. I have all my BOT stored in a bag "just in case". I had a vet who's husband competes tell me that they ice their horses and she feels that heat does more damage. I don't know why, it just always stuck with me what she said, so I use the PHT. My horse loves the sheet.

I'm scared of BOT because of the heat, especially with most of it being black.  It's hot here in the summer.  I can't see where that would be good for them. Never even bothered to try it. 

I love my PHT stuff.  I've seen results with the hood and the stifle wraps. The stifle wraps even surprised the vet on recovery time for an injury.  The hood loosened my horses neck up enough that it Finally adjusted (took a full summer to get it to even move) and then remained in place!  He was roped on and his neck was a MESS.  

My old gelding snorts a dozen times when you put on his PHT as he relaxes. He's 25.  I've put on other plain blankets and no snorts. 

I've also used the PHT wraps on my knees and for female cramps.  You can feel it tingling and then pain goes away.  The cramps going away was amazing, as meds didn't do a darn thing. 

I have both. I use my BOT leg wraps religiously in the fall/winter and spring. It is to hot where we live to use them in the summer. I love my PHT blankets. My horses will fall asleep with them on. They only get them in the trailer, when tied or stalled. I worry about the heat issues with BOT esp in the spring/summer in OK so I went with the PHT sheets. You can put them on wet and my horses love  it in the summer. I have noticed a significant difference after using my sheet when they are sore, after a 3 day race or an adjustment. They recover faster and are less stiff/sore. I have happier horses when they get to wear them.   

Love reading all of the responses. Thanks all! 

I swear by PHT/Magnacu.

I usually put my geldings magnacu on before we leave and only take it off for our run. He lives in it on the road. 

I sent him to a derby with a different jockey last may as I couldnt go and he was a contender for the year end. I didn't send his magnacu with him. 

He came back looking way worse than I'd expected... no fault to the jockey. I sent supplements and hay and I trust her emmensely.

Last fall, the same girl borrowed him to run at a pro rodeo that I didn't get into. I sent his magnacu with him this time. Way scarier haul, way tougher experience. He came back looking great. 

We also had an old gelding get hurt pretty bad a few years ago and need to be stalled for several days without exercise. It was very very cold, mid winter, and he already struggled with arthritis. I was terrified to see him after three days stall rest. I tossed a magnacu on him. He walked out of his stall three days later sounder than he went in. And, his wound (which had 100+ stitches which was the reason for the stall rest) was clean, minimal swelling and looked great. This incident is what started my love and trust in magnacu. I have yet to find a horse that doesn't feel great wearing it. 

You won't appreciate how the PHT works until you get a knock off that makes your horse sick.  PHT is well worth the money.  

This is interesting. How did the knock off make your horse sick?
