These were so stiff. I threw them away after two wears. Way too stiff.

Not what i wanted. I was looking for a different product. These were really stiff - even more stiff than twizzlers or red vines. Much more rubbery.

The only thing I liked about these were the different colors to identify my cards, but they were too stiff and bulky.  They stretched out our wallets.  I'm exchanging them for something made of a thinner, more-pliable material.

Too stiff and too narrow. I don't know how I could possibly exercise in these. Maybe people can wear them for walking around. Not for me!

These were very disappointing. The PU leather is super stiff and not flexible at all. When I grabbed the bar, the pu leather did not bend with my hand, and created a different surface for my palms to rub against. It was in fact more painful on my hands than without them. My friend has leather ones, and her are much softer and conform to the hand better. I would get a leather pair and not this set.

These bands are incredibly stiff.  You definitely need to wear clothing underneath or they'll be extremely uncomfortable.  They are also difficult to get sufficiently taut.  Very disappointing.

Stiff as a boulder. We have taken to using these as back support when sitting up, may be right for some people, just not for us.

Really stiff fit, not comfortable at all. Returned them.

NOT SOFT!  Horrible stiff, "hard", shiny material.  Feel like they've been sprayed with a stiffener.  Ill-shaped.  I can't imagine these would fit anyone.  Too big in the back at the waist.  Low-rise.  Skinny leg, just as advertised and small at the ankle.  Colors are nice.  I'm sending these back.  I don't know why hybrid products are so inconsistent with the sizing, fit, cut and material--even between colors!!  I had to order so many to try on since all the reviews said how inconsistent they are and they are right.  Everything about them is inconsistent.  I've never seen such a thing.  Cheap inexperienced seamstresses?  No quality control?

Won't recommend it.  Too stiff.  Does not open much..  Quite useless.

No stretch which I like but didn't care for the mainline its stiff and has a mind of its own. I prefer Hyperlite's silicone line which has no-stretch but is much more flexible.

Fabric is stiff, thicker fabric. Not form fitting.

I ordered this mattress based on all the great reviews.  Unfortunately it is MUCH firmer than I was expecting.  I am a 6 foot tall man and weigh about 190lbs, and even at my size, there is barely and contouring to my body when I lay down on the mattress.  It is extremely stiff, which makes sleeping on my side all but impossible.  I have been waking up with my arm completely asleep and pain in my back and neck.  There is no flexibility or bounce at all.

I bought a mattress topper to try and add some additional cushioning, but it has had very little effect.

I am very tempted to return it, but packing this thing up and shipping it back is no easy task, so I think I am stuck.

Moved into a new place with a typical small shower head and was pretty well clogged. The add insult to injury, the shower stall is tiny (2.5'x2.5'), making getting under the shower head difficult. I bought this Waterpik with flexible neck, thinking I could adjust it into an overhead position or the like fairly easily.  Turns out to be a bust though. The neck just isn't nearly flexible enough, and it't not something you want to be adjust often. Very, very stiff. The way the description makes it out, one should be able to easily adjust into nearly any position, and that simply isn't the case.  Installation was easy enough, and a little plumber's tape and extra tightening on the end result is a leak free setup.  For what I needed, this model didn't work, and I ended up getting a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Water-Ecoflow/dp/B009CEY06K/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Water Ecoflow</a>, which was both cheaper and did the job.  True, it's not a rainfall type, but that wasn't what I needed anyhow.  Instead of returning this one, it's been moved to the guest bathroom, where the lack of flexibility isn't an issue.

Not very comfortable.  The plastic is much too stiff for my feet.
