I purchased this product and my IT professional advised me that the disc may be counterfeit since the holographic surface on the disc is a sticker and is not embedded in the disc

You never are sure when you buy an item like this. Maybe it will work and maybe it won't. So far I haven't contracted any virus so.....

Essentially, this product functions as described on the tin. I quite like it a lot, and think its a groovy addition to my growing interests in the stars. Side note: This is not a child's toy (or toy for that matter) unless that child enjoys reading star charts.

This single cup brewing system is well designed and works exactly as expected. I can brew fresh coffee for my 16 oz. Aladdin Travel Cup and it is an easy, fast and awesome coffee making experience. It's over-sized top acts like a rain gutter to channel any boiling water back through the filter and into the cup. I love the permanent filter bag, it's so much more convenient then buying filters. I just brew my coffee then dump the used grounds into the disposal and rinse the Primula Brew Buddy well and hang it to drip dry. The whole process works like magic and makes an excellent cup of coffee every time. I can find no faults at all with this product & like the versatility of taking it on trips or when camping. Fast, simple and easy would describe using it. I highly recommend this product to anyone and for bachelors like myself who live alone, it really fits the bill. Buy it, you won't be disappointed.
