Review on OliBoPo Waterproof Replacement SGW 300H MRW 200H: Ultimate Protection for Your Watch by Ashley Martinez

I bought this for my Casio W-735H, the parts arrived right but upon installation I found they weren't quite the right fit. Since I had the choice at the time of modifying this part to make it work or not wear my watch, I trimmed the excess material off of it and was able to complete the installation. This will of course prevent me from returning it instead. The rest of the strap is fine, I only had to replace half of my strap first and it fits perfectly in the same notch as the factory strap. I then had to replace the other half of my group and encountered the same problem. There must be an issue with the mold they used to make it, or maybe some excess resin was the culprit, but the bottom line is I had to cut out the material to fit it. I would not recommend purchasing this item when I also have a W-735H, the amount of material I had to remove was more than would have been necessary to "easily" complete the installation. Although so far I haven't had any issues with the durability of the strap.
