Not my favorite
Size: 24 Double Rolls (2 Ply)
I've tried quite a few bamboo toilet paper brands, and this isn't a favorite. Even at 2-ply it's thin. It has a good texture while being soft, and lint free as advertised, but I find we use more of this brand due to it being thinner. It has a lower price point than some of the premium brands, but a classic case of "you get what you pay for" and since we use more it doesn't really save any money anyway. Also it says plastic free, but comes in plastic packaging - it's not clear if it is eco-plastic/ biodegradable or not. It's not a bad product, and everyone likes something different and has their own priorities, but personally I won't reorder.

Good quality and absorbancy
Size: 24 Double Rolls (2 Ply)
Was a little leery about bamboo toilet paper but I was tired of the how, even the 3 ply expensive toilet papers I've been buying, were not very absorbent. I must say I am pleasantly surprised. The sheets are smaller but they don't fall apart like the others and I think they are very absorbent even tho, at first, you don't think they will be. Will definitely buy this brand again.

High value, low price, minimal packaging, good deal
Size: 24 Double Rolls (2 Ply)
I would rather give 4.5 stars but it won't let me so 4 it is. It functions as a TP should, it is strong enough for dry and wet use. It is comfortable and pretty soft feeling. It is noticeably thinner than the other ones I have tried like amazon and gaias bamboo, though it is still fine.
For 39c per 100 sheets, it is one of the few lower priced TP's that I've seen and it performs well enough that I will most likely keep buying this brand. Amazon bamboo is about the same price per sheet, but the amazon one is very rough. Honestly I'm more concerned about value here myself so my current rotation of bamboo TP will be between eco brand and amazon.
I like this eco brand and I appreciate their minimal packaging. I would recommend the eco brand for the soft feel and low price per sheet. Keep in mind some may think it's a but thin. I would recommend the amazon bamboo for it's low price and strength, but it's very rough. So far these are the main two options I've seen for lower priced bamboo TP.
In comparison to say costco TP, the kirkland blue wrapped standard TP is about 33c 100 sheets. The charmin ultra strong red packaged one is about 43c per 100 sheets so this eco brand bamboo TP is well priced considering the market.
From what I've seen, in order to have everything a person could want in a bamboo TP, strength, softness, wet and dry performance, they cost a lot more than this one and personally I wouldn't bother if these lower priced brands work instead.

Soft, cool, good size
Color: Gray, Size: 18"x24", Color: Gray, Size: 18"x24"
This bed is pretty nice! The cool sides really stays cool all day. My cat is still getting used to it but I think it’s a great addition for summer. It also seems like you can just put it in the washer to clean it.

Good product.
Color: Gray, Size: 18"x24"
I live in Michigan so we have cool nights. We have hot days. Last night I went to pick up my new cooling mat to put it up for the evening and was totally blown away at how cool it was to the touch. For the price, the quality is outstanding. I will be purchasing more in the future once I know that my cats will use it. We haven't got that far yet, but once they do I will try to include pictures of them using it. I hope this helps someone as I am pretty picky about what product I buy. I was thoroughly impressed. The back side, or the warmer side is very soft and perfect for winter time use. It was an absolute genius idea to make one that is universal.
