The Colby CX-90 looks great, especially the digital readout in this price range. The clock is a nice feature, and the slender vertical size makes it ideal for slipping it into a pocket. I found programming the presets (10 AM, 10 FM) and the clock fairly easy. Those are the positives.
Now the negatives. Many people have complained about the lack of an internal speaker, however I knew this before I purchased it. Also, remember that the FM is mono, not stereo. The tuner sensitivity is mediocre at best. Even strong stations come in a little scratchy at times. The markings for volume, memory, presets, etc. are nearly invisible, so you either need to squint or memorize what button does what. Early on I fumbled around often with these.
In my opinion, the minimum volume setting is way too high, and I will probably never go above 3/16 on AM and 7/16 on FM. The unit seems to eat batteries, maybe because the clock is always on. I would highly recommend rechargeables, or this will end up being an expensive cheap radio.
Knowing what I know now, I would likely not purchase the CX-90.
