Sturdy, accommodates harder to fit bottles

Sturdy, accommodates harder to fit bottles, and you can actually double stack bottles for additional storage. So versatile!  Great buy!

Sturdy, good quality and easy to install. We use it with just the lower shelf, without the upper shelf in order to store taller bottles. Came with all necessary screws, and instructions. Love it.

I was able to modify it to the existing holder.  I like the way it is adjustable to take different bottle sizes.  However, be careful when adjusting.  Too much pressure could break it.  Otherwise it is a great bottle holder.

This is a solid water bottle cage. I have been through a few different cages over the years of mountain bike racing. We usually race over a 12-hour period and have to use insulated bottles to keep the contents cool, so they are a little thicker than the average squirt bottle. The pictures show the insulated camelbak podium bottle. They are a tight fit, but that is good, I have had a bottle bounce out of other cages when going over bumpy terrain. With a little work you could shape the metal sides to accommodate a slightly larger or smaller bottle. I placed this cage over my mini bike pump and it fits well, no obstruction to the pump or bottle. The bottle cage came with two allen screws, but I used my longer screws to accommodate the bike pump.

Fits well on my standard bottle rack but it IS very long. Nice to have the extra water it carries. The top is well made with excellent heavy-duty screw-on threads. Solid construction (ie; NOT flimsy).

I needed a cart to fit between my washer and dryer that could hold larger bottles. As I have it spaced (lowest shelf on the bottom rung, middle and top on the middle rungs), there are a little less than 12 inches of space on the bottom shelf, and a bit more than 10.5 on the middle. Four stars instead of five because it tends to lean when pushed/pulled and lacks the bulk and rigidity necessary to roll well when full. However, I don't need to roll it far - just pull it out like a drawer to retrieve the bottles. Many people will not put six heavy bottles on it, either.

I put this together by myself in about five minutes, and I didn't even bother with the instructions. It does require a little effort to get the middle and top shelves in place. Put the shelves on from the bottom up, one side at a time. I popped up the middle shelf on one side to put the top one on, but it wasn't all that difficult to re-seat it. The top shelf - I wanted to put it on the highest rung, but the straight tabs on the end of the shelf will not fit between the sides' large frame posts unless you move the shelf down to the second rung.

With all that said, it rolls well enough, I'm not worried about it coming apart (I'm not storing delicate china on it!), and large bottles fit when you put the shelves in the right spaces. The alternatives were just WAY too expensive for pre-fabricated wire pieces, and I don't think they could possibly be that much better for the price difference, since almost all of them are put together the same way.

Love this item as it makes storing water bottles so much better.  The plastic is of good quality.  I just wish it didn't take up so much room in my fridge.  Maybe if they made it so you could store things on top of it as well?

These are super sturdy and fit a good amount of little bottles.

Tight seal on even thinner bottles, great choice!

This is a fantastic product. It seems to me to be more useful for cans than bottles, but it does accommodate both.

This is a good product for what it is. It does indeed hold 81 bottles and makes the colors pretty easy to see in the standard bottle.

It is sturdy and makes organization much easier.

The lack of a four or five star rating is that some of the rack slots are slightly smaller than the should be. You MUST rotate the bottle clockwise to inset or remove them from the rack. The reason you must rotate them clockwise is because if you try to remove or insert a bottle and twist it counterclockwise you unscrew the lid and are likely to spill paint all over.

However, with that said I would purchase again because there just isn't anything I have found that will hold all my paints.

Easily fits standard bottles of nail polish, and have been able to pack all of my nail supplies into it. Heavy objects start to distort the sides when trying to move the box, and connectors have opened when picking it all up with only the handle. I have 80+ bottles of nail polish in it, however, so this appears to be a weight issue. Also fits loose-leaf and printer paper just fine.

Very thick and insulating.  Lack of flexibility limits fitting any bottle but longnecks, however.

Difficult to put together, bottle holders are sized differently so one of two bottles of the same size bottles doesn't fit. Bottom not level, wobbles.

The bike cage is only a little bit more expensive than the aluminum wire bottle holders, but it holds the bottle a lot more securely. The design with the arms on the side of the bottle allows it to hold more sizes of bottles than the standard bottle holder that just grips it at the top. I have not had a bottle fall out from this holder. Easy to install and came with additional screws in case your bike does not already have them.

Sturdy bottle. The top is easy to remove, making it easier to clean. However, the bottle is a little narrow, so it's very difficult to clean the inside of the bottle unless you have a bottle brush.

Works well.  Can hold two good size insulated bottles.  Can fit a waist >42 inches.
