Review: Great ho train track but my only complaint is it was shipped in a thin bag - Kato enough said
Review: Kato products ROCK! - I have always been a big fan of Kato engines and rolling stock, and have owned N scale unitrack in the past. I switched to HO scale a while ago and have a ton of Atlas track. I was reluctant to go with Kato Unitrack because of the cost. I decided about a couple of months ago to pull the trigger and give it a try. Happy to say, there are no regrets! The track looks awesome and is so easy to work with. Joins together and comes apart very easily, and stays securely connected. Great for temporary or permanent layouts. If you just like to throw track on the table or floor without messing around with scenery, then you will be able take your ideas and change the layout in a snap, and be confident that everything will stay together and in one place. As for the Atlas track; giving some to my neighbor and his little boy, and the rest will be on Ebay. Kato unitrack is worth every dime. Just make sure you shop around and compare prices. You can find great deals like this one, and you can get screwed by someone selling it for much higher prices.

### ⭐⭐⭐⭐⭐ High Quality Product
*by H***R on March 17, 2020*

Kato Unitrack is an outstanding product. Very easy to assemble, very easy to take apart, and gives you a very smooth track surface over which to run your trains. I have already assembled and disassembled my layout a few times and it works like a charm. Very easy to change track layout. Highly recommended product.
