Very small dollys. Cheap wheels. Ok if you are going to use them very rarely.

These dollys are very small. The pair for the skis work ok, but the one to go under the track is tiny. I wound up using a furniture dolly under the track. The wheels are cheap and I suspect will fail with regular use. I wish I had spent the money for a better product.

Bought these to go with the Breyer stable. They are very small. My daughter is 3-yrs. and I was hoping the horses would be bigger and be able to stand upright easily. I would not recommend these nor the plastic stable.

This is worth less than the price. It is functional but cannot be moved at all once filled with items. Does not come with wheels. I bought wheels separately and it still had a really tough time moving around.

A decent cart, for light usage. The material seems to be very cheap and flimsy, considering the cost of the item.

Depending why you are buying this, a wheel barrow might be a better choice.  I bought it to haul heavy items such as marine batteries, tools, and other items from a parking area to the lake, about 1/4 mile.

Pros:
No solid thumbs up on this item. It is OK.
Assembly was easy.
Cons:
No way this is rated at 600 lbs. Off the cuff I give it about a 250 lb working capacity.
Grade 2 nuts and bolts
Terrible wheel spacers, and a likely failure point
The weakest part of the assembly are the dumper sub frame and the handle. Both important.
Handle is to short for anyone taller than 5' 10" requires you to stoop.

If you are doing light work around the yard, and plan on storing this inside most of the time, this wagon is OK, if you plan to be doing harder work consider a higher grade wagon or a good wheel barrow.

They are cheap but very low quality. The handles fell apart 3rd time I used. it cant handle much weight

Very small. The table had a damaged corner and the rubber seal won't stay inside. One side of the tables does not have the plastic clip that keeps the chair inside and the chairs only hold the weight of my 3 and 4 year olds and they tip over easily. Very cheap quality and small not worth what I paid.

The cart is good for short trips from super markets and laundry but the wheels are made with plastic. not long last.

very cheaply made. you have to put some of the toys together yourself.. the small parts are in bags unassembled. I don't expect they will last very long before breaking.

I would caution anyone who is looking for training wheels to not purchase these. They are made of very thin metal and within 10 minutes had already bent outwards even with stabilizer on. They are very inexpensive and I guess you get what you pay for. They may work on a 12 inch bike with small child but would not trust on anything larger.

This is definitely a low quality product.
I bought the extra large heavy duty black model. It's definitely not heavy duty. The metal that connects the wheels is flimsy at best. It's hard to turn the cart around and the pin the keeps the wheels in place might as well be a paper clip.
The instructions are not helpful as well but it's just connecting a couple of wheels so that's not a problem.

I would not recommend buying it.

I wouldn't recommend this, especially to little kids! First, its very flimsy, not stable at all and with the 1 wheel in the front and 2 on the back makes it completely easy to fall, tip. Second, it's cheap parts and not made well.

The ;legs folded up on it the first time we used it and one of the wheels kept falling out. VERY cheap. Save your money

Reels are too small.  They will not hold very many lights.  I sent them back.

Really cheap.  Wouldn't last very long.  The wheels are plastic not rubber.  Plastic on the top of the handle.

The ONLY thing I did was remove the handle & wheels.  The 3" cheapies, were more trouble than they were worth.  Bought a $30 folding dolly/cart from Lowes as an alternative to those useless wheels, and the too-short handle.

I did not like this item.  It doesn't serve the purpose.  It's hard to roll without it tipping over.  Too small and not sturdy.  I end up carrying the bag which defeats the purpose of having wheels.
