Review: Poor quality - Arrived quickly with no issues however the red filter lens was extremely loose and rattling around in the ring. The Magenta one was solid and did not rattle however had to return for refund so cannot comment on the product in use. I still need the expansion arm so will probably order another but annoyed that I need to now be out of pocket buying another and having to go to a drop off for a faulty item and then wait on a refund.
Review: As described and good quality finish - As described Would like the ability to mount both filters rather than have to swap them out Used it on a weeks sea dive - will see how it holds up to seawater

## Questions & Answers

**Q: [Smartphone Function] Why is it suggested to remove the smartphone screen protector film before we put the phone in?**
A: There is a thickness of the membrane itself, with the thickness of the screen protector, the sensitivity of the touchscreen could be lost. the thin plastic screen protector might cause a problem of phone stuck in the housing.

**Q: [After-sales] My smartphone screen was off underwater and I couldn’t turn it on again.**
A: Please check if the smartphone function is well setup according to the guideline, such as turn on Raise to Wake on iPhone or turn off Mistouch Prevention on Android phones.

**Q: [Housing Function] Does the housing work up to 60 meters?**
A: The touchscreen operation of the SeaTouch 4 MAX housing works even at the depth of 60 meters. However, it is suggested to use above 40 meters because the high pressure could compress the housing to deform, leading the sensitivity to reduce gradually.

**Q: [Housing Function] If I change a new phone later, can it still work in this housing?**
A: One of the feature of SeaTouch 4 MAX housing is its modular adaptor for different smartphone. With different adaptor, the housing is universal for a various number of phone model. Users just need to buy a new adaptor to fit in with the new phone.

**Q: [Housing Function] Can it be operated when I wear gloves?**
A: It is operable while wearing wet suit gloves underwater. However, due to most of the dry suit gloves made by insulating material, it has to be a conductive cot on the glove to operate by touchscreen.

### ⭐⭐⭐⭐ As described and good quality finish

As described Would like the ability to mount both filters rather than have to swap them out Used it on a weeks sea dive - will see how it holds up to seawater

### ⭐ Disappointing and not worth the investment
*by R***S on 2 October 2024*

I recently purchased the lens attachment for the SeaTouch 4 Max, expecting it to elevate the functionality of the base unit. Unfortunately, I was left feeling that this is a feature that should have been included in the original SeaTouch 4 Max—and after using it, I can see why it wasn't. Straight out of the box, the attachment's metal components were covered with an odd, multicoloured, oily sheen giving it an eroded look. This immediately raised concerns about the quality and durability of the materials used. Worse still, two of the mounting screws showed signs of rust or corrosion before I even touched them, which is unacceptable for a product designed to be used underwater. When I attempted to attach the unit, the screws wouldn’t thread in properly, making it impossible to securely mount the lens. Even if I had been able to, the fit was poor. It felt like the attachment was too small for the base unit, causing it to bend in areas where it clearly shouldn’t. I wouldn’t trust putting any additional attachments onto this, as it feels like the whole thing could break under pressure. Overall, this attachment falls short of expectations. The fit, finish, and durability issues make it hard to recommend, and it's disappointing that such a key feature was left out of the base model, only to be executed poorly in this add-on. Not worth the investment.
