Missing collars makes the dumbbells unusable

This product was missing the 4 collars. Thus, the product was not usable from the very beginning.

Only fits the tiny kettlebells. So far they have offered me only 35% refund, despite the fact that their kettlebell stand is made so that kettlebells won't fit on it.  Completely useless!

Each shirt arrived missing the holes within the strap to secure the sleeveless if worn like shown. Had to take to a seamstress to add the missing holes; additional money spent! This leaves me to believe these items are true irregulars. What a shame!

The bars look and feel nice, but the collars do not always stay on tight. The dumbbells do get the job done, but I have to tighten the collars after almost every set.

I have a different brand of dumbbells, not sure what brand though, and that pair works fine and the collars do not come loose.

I've had mine for a couple of years now. I use them all the time. I recently discovered that there is an accessory that turns the dumbbells into kettlebells, but it doesn't work with this model, so consider that if you're interested in kettlebells.

One of the two pink dumbells (3 lbs) is deformed and is missing some material. It does NOT weigh 3 pounds.

Product not only arrived late, but crucial parts were missing. I was excited to get my first trainer. I'm working toward my first triathlon and the bike is my weak link. Imagine my disappointment after waiting on a prime item 5 extra days the discovering it's basically useless. The magnetic tightening knob and the wrenches that were supposed to be included in order to assemble the item were not there. Now I'm having to box this thing up and truck it to UPS to return it. I don't recall having ever left a review on a product before, but this just tipped the scale for me. Other than these things, the instructions for assembly are not really clear and the manual says it comes fully assembled which it does not.

Ordered this rack in July, received it in September.  Upon trying to assemble the rack, I found that the Up Outside mast is missing, and the ring bolts are too short to even attach rings.  Too late to return, as I waited too long before trying to assemble it.  The rack is useless without all the necessary parts -- TOTAL WASTE OF MONEY!!!

I bought this because it apparently has a collar at the top to hold the bag. I put a standard 13 gallon kitchen bag on it and it doesn't reach the bottom of the holder. The collar doesn't hold the bag so as the bag becomes full it slips out and is more of a problem than what I tried to solve with this item. I had to put something under the bag to hold it up which looks sloppy. The opening is smaller than it appears in the picture but that is acceptable. It is not "collapsible". It must be disassembled to store or move. I think I'm going to return this item.

All the features worked great until one of my boxers managed somehow to get her unit off of the collar and chew one of the plastic tabs off that holds the collar in place. Now I have to figure out a way to modify that end of the unit so that it will stay on the collar. I bought this trainer this past December  2014 and just put it on her this past Monday 3/2/15 and cannot return it because the return window is closed. I would not buy this model where the collar straps squeeze between the tabs but  buy the other model where the strap collar pushes through like a belt loop. The vibration mode really works great! Have not had to use the shock feature on my other boxers.

It is almost impossible to screw the jeweled ends into the barbell. I tried in so many ways and eventually gave up.

one of the Spin-lock Collars Screw was wrong size and i couldn't find any spare.....so the whole set is rendered useless....to be fair. i was given a refund for that lock, but at the end of the day, it didn't solve the problem.

Expect to buy new collars with this bar. The sleeves on the bar give a lot side to side.

The collard came with a cut on the closing part of the collars.  There is very little I can do

Horrible product. The box spring requires assembly, however it arrived with half of the bra and wing nuts needed to assemble it. Also, 6 of the 10 cross support bars were missing. The quality was so poor, that even if assembled properly, I doubt it could support the weight of two adults
