    Rated 4 out of 5 by from Great support 14 months ago, my daughter's horse (18 years old) incurred a severe injury to both back legs, opening the legs to the bone and partially tearing one tendon. I immediately went to smart pak and started him on tendon and joint supplements. While he may never have the same flexibility he had previously, we started trail riding him again this past summer, and he is completely sound and never wavers or appears to be in distress. He's a very picky eater and will eat these.

    Rated 4 out of 5 by from Seems to be working... I started my 4 year old mare on joint supplements after she was diagnosed with OCD in her hocks. After her initial diagnosis and lameness I started with the SmartPak Rehab then switched to FlexII. She seems to be doing well so far without additional medications. We'll re-evaluate once shes put back in work. I will say shes not crazy about the taste but its no where as bad as the Rehab pellets. After smelling them, I'm dont blame her - I wouldnt want to eat that either.

    Rated 4 out of 5 by from A good supplement I've been using this supplement for a little over a month and I definitely do see a different in my horse. She's less stiff and seems much more comfortable. The price did just go up on these supplements, but I do plan on continuing to use them.

    Rated 5 out of 5 by from Great Ingredients So far, so good. I used another product for years but found for the same potency (really even more!) Smart Pac was cheaper

    Rated 4 out of 5 by from Decent Product I bought this for upkeep with moderate amount of arena/trail/playday riding and find it is doing a good job keeping my horse healthy! The pellet form is good for my picky horse who leaves powders at the bottom of her feed pan.

    Rated 5 out of 5 by from Awesome product I got a mare off the track and she was so stiff! I tried other products before this and after a week on this, she was moving so freely and wasn't stiff one bit! It was amazing the transformation.

    Rated 5 out of 5 by from Amazing Joint Supplement Back in January my horse cut her hock joint. It was very bad and I was afraid I wasn't going to be able to barrel race her any longer. She is now healed completely, and with the help of Smartflex II, she hasn't taken one bad step. She eats every bit of it, matter of fact, I think she likes her feed more with the supplement in it! I will recommend this stuff to anyone that wants to give there horse that extra support with their joints!

    Rated 5 out of 5 by from Great product! My old guy has been on this for a couple of months now and it's doing a good job of helping him maintain his mobility. Bonus: he eats it! Definitely keeping him on it.

    Rated 5 out of 5 by from Just enough support without breaking the bank I have had my 4 yeat old mare on smartflex II for a few months now and she is moving more freely than ever! Its nice to know I don't have to spend a fortune on a quality product and I don't even have to worry about ordering or picking up the product with Smartpak's auto ship program.

    Rated 4 out of 5 by from Great supplement, picky eater approved! I decided to give this a try a little over a month ago because of the 50% off sale smartpak was having. My mare gets joint supplements in the summer months (she is not really worked any other time of the year) and these kept her moving great! She sometimes gets a bit stiff without a joint supplement or with lesser supplements, but this worked great! In addition, she is a super easy keeper, she gets absolutely no grain in the summer, even though all she had in her bucket was her smartpak, she licked every bit clean, she loved it!

    Rated 4 out of 5 by from So far greatness!! I've only been using this product for 1 1/2 months but seems to be working!! Love the ease of the smartpaks!!

    Rated 5 out of 5 by from Peace of mind I started my 6 year old mare on this supplement. She is in training for dressage and is ridden 3 or 4 times a week. Although she has not exhibited any joint issues in the past, using this supplement gives me peace of mind that we will hopefully not encounter significant joint issues in the future.

    Rated 4 out of 5 by from Great Product My horse has done really well on this product for the last year, he is around 25 and still does play days and runs his heart out...I am switching to something a little stronger just to see if I can see any difference, but for the great price, this product really seems to work...you have to try it for at least a month to get into their system and stay consistent just like any other product, but I would recommend this..
