I've been using the old Cateye Micro Wireless for years (ever since they came out), plus a couple of VDO's, Vetta's, and Cateye wired. I thought it was time for a new toy. Decided to stick with Cateye. I looked at a couple of online videos before my Slim arrived. Programming was not as difficult as I anticipated. I did not have to resort to reading directions (but men never read directions anyway, right?). The hard part was pushing the tiny little reset button. I used the tip of a pencil, probably not the best device to use. Set-up was fairly easy, sort of the same as the Micro Mini, if you are familiar with Cateye computers. The computer head is smaller, the digits are larger (I compared it side to side with my old Micro). I installed mine on my stem. A little muscle was necessary to get the rubber mount band to co-operate, but once it's on, it's on.The diff between the Strada Universal and the Strada Slim is the road sensor. Basically the same as the old wireless Cateye sensors. One thing I like about the operation is the push on the computer head (not too long, or you will loose all your information, except your odometer reading). to get readings. Nice in the winter when you are wearing long fingered, bulky gloves. The computer will go to sleep after a few minutes, so you have to remember to restart it if you take a break on a ride. If you want a basic computer this should fit your bill. It's small, compact, non-cluttered appearance. Excellent Cateye quality. All the parts are replaceable through Cateye. The only improvement would be saving odometer reading when installing a new battery.
As a certified retro grouch wo a Garmin, I have owned several Cateye computers over the years. This is the best one yet. It has all the basic functions you'd expect and need from a cycle computer in addition to the wireless connectivity, which is a must in my opinion. Where they improved this computer is the larger display which is much easier to read at a glance. The mode button has also been improved with a simple tap that pushes the button on the underside. The stem mount has also been upgraded wo using zip ties - no more ouch. For the money, anything with wheels that you own should have one of these.
