I ordered this kit for my Garmin Dezl OTR700. For one, the torx bit that was included wasn’t the right size. Not too bad of a problem as I have a set of small torx bits from harbor freight. But more importantly, this kit came with 2 batteries with 2 different plugs designs. NEITHER ONE WORKS in my gps. Both were too big to plug into the connector. Also, the only instructions that come with this kit are on a DVD. I don’t have a DVD player anymore as I stream all my movies. So that is useless. If you insist on using a video for instructions, give us a link to YouTube or your website.

My rating is my first impression of the entire package, without knowing how well the battery itself will hold up. The battery was a higher capacity than the original, and physically larger. There was space in the DEZL 770 for the larger battery, that had been filled by a plastic card the original battery was stuck to.The original was an 1100 mAH single-cell Lithium, while the replacement was a 1500 mAH of the same voltage. The Torx driver included appears to be a T6, while the 770 required a T9, which I already had. The pry tool included is something I'll probably use again. It does the job and seems to be made of quality materials. The disc included was for a DEZL 760, which is very similar, and possibly explains the incorrect driver.The Garmin powered up and is currently charging fine. The original battery would only last about 5 minutes, which wasn't critical, but the device was occasionally resetting while plugged in and tracking, which I'm hoping was due to the battery being at the end of its life. Considering the price of this battery, compared to buying a new GPS, this is really a bargain if it solves the issue. If not, it'll still be a good spare if I buy a new device, with a good battery.I can't comment on the video disc included, because I didn't use it. Replacing the battery isn't difficult, but does require some care. For someone who's never done something like this before, it might be a good idea to get a 10-year-old to help. I've been taking things apart for at least 55 years, and most of the time can put them back together. My philosophy relies on the fact that if it's not working now, I can't either fix it, or screw it up bad enough that it'll need to be replaced.
