Question: is it backlit
Document: Having issues with this working only some of the time. I've re-positioned the sensors a couple of times but doesn't seem to help. Sometimes have to slide the computer on its perch (where it makes the connection to the wired sensor) to make it work, but that doesn't fix it 100% of the time either.... Wish it was backlit too, most of my riding is done at night after work...
works good use it every day, 128 miles a month kind of thing now and can calculate it digitally instead of map and ruler. I would recommend it to anyone I know.
works fine...better price than outside Amazon, as is usually the case...time will tell, but so far, it's great...(fixing up my girlfriend's new bike I just bought her)...she's happy
very disapointed, came out of its holder on the second ride. i dont think i ride that hard so very upsetting when i looked down to see it gone, even tried to retrace my ride but no luck...also didnt like the snugness/fitment of the wheel attachment sensor peice, it seemed to always be loose and come out of position.
the item came rather quick , but when installing it, I had a defecive item. I contacted the seller and immidiatley told me of theissues and was  quickly refunded. Seller was very fast to fix my predicament and I thank them for their prompt and courteous customer service.. thanks so mmuch for your time and help on the issue. would of given 5 stars had i been able to use the product but i cant  use it due to its defect.
the bike computer works great I loved it to fit perfect on my ezip trailz bike. great deal for the price
the  only  thing  i  don  t  like  is  that  the  extension  cord  is  too  shorti  m  supposed  to  use  it  on  the  back  wheel  of  the  bikethere is not  enough  lenghtit s  an  indoor  bikei  m  not  using  it  now
regardsthanks for letting the product catalog, is practical and ergonomic, it fits my needs and has good performance. It would be better if the cord was longer, maybe about 15 cms to fit better in the cble brakes and having to touch the suspension. recommend, thanks
put on bike easily, batteries working, but its not keeping track of milage etc yet, going to take it to a bike shop to have them perfect it, and hopefully it will work then :)
product did not work. pain in the rear to install on bike to have it not work was quite irritating
Answer: yes
