the product idea and form factor is great, and i have ordered 2, and both died within 2-3months of light usage.the worst thing is that the company do not stand behind their product. where i purchased it from Amazon (official Amazon.com, not 3rd party), and Rolling square refused to honor their warranty for the product.given the repeated failure (in such a short time), it's not worth the $20 price at all.And the business practice is also very deceiving (how can company like official Amazon.com consider not an authorized retailer...)

Was sceptical at first. But they delivered well. The package arrived in 9 days and all parts were accounted for. The incharge 6-1 works well and is worth the wait which isn’t that long to be fair.

This thing is actually really nice, sometimes PD/QC works. -

This product is great. Small and light. Great for value for the money. -
