### 2/5 — Not operational

*2025-03-09*

Product no longer works after upgrading to iPhone Pro 16 Max.

### 1/5 — USB C

*2025-01-17*

Won’t work with usb adapter or with the android version of the thermal imager

### 1/5 — Does not work with the new iPhone

*2024-10-30*

The new iPhone has a usb-C connection. Klein does not support the use of the USB-C model…..

### 1/5 — Does not work, at all

*2023-11-25*

Plugged in to the USB’s port, and the app does not see it at all. USB dongle is way too short so you cannot use it with any case, or need some adapter or extender. Currently this purchase has been a complete waste of money as it does not work at all.

### 2/5 — iOS usb-c

*2023-10-18*

Won’t work with adapter hopefully it will work with an update

### 2/5 — Needs improvement

*2023-08-02*

Seems to do what is advertised. Would be nice with no water mark. 

Phone overheats and dims the screen while using this app. 

App tends to freeze for a few second every 30 seconds or so. 

Would be a good improvement if I could generate a report from the app. 

Does not rotate image when trying to get a landscape picture.

### 2/5 — Forced watermarks should be removed

*2022-10-16*

It’s ridiculous that this app requires you to accept a huge Klein Tools watermark on every photo you take.  It’s the top complaint about competing products in reviews - Klein should learn from that mistake and offer an option to disable the watermark so you can see the full field of view of your images.

### 3/5 — Functional but needs works

*2022-09-29*

The hardware works great and feels very well constructed, though the lightning connector is minimally short, so it essentially can’t be used with a phone case without a cheesy import adaptor or extension cable. Seems like a major oversight for a device from a company that caters to trades people.

The software functions. As other reviewers have noted, it needs serious refinement.
1) camera rotation. Since the hardware plugs into the bottom of a phone, you essentially block it with you hand while holding it, so you have to rotate physically to landscape, but the app doesn’t. 
2) remove the Klein logo/watermark. Totally unprofessional to have that in images that might be used in reports; and I’ve already purchased a Klein device in bright orange that is hanging off my phone. Branding on the images and videos is insulting. 
3) microphone mute/disable on videos would be a great nice-to-have

### 4/5 — Decent but needs improvement

*2022-08-31*

Overall the app does what it should with the imager. However it could be improved. Here’s a rundown of what needs to be included in a future update:

1. App/Imager details needs to rotate with screen orientation.

2. Ability to remove the Klein logo and/or add our own. This point seems a little unprofessional on the part of Klein given the cost of the imager.

3. Ability to adjust/tweak the focus (if this is even possible).

4. Ability to mute microphone/audio on videos when recording.

Again, app does what it should especially given that it’s v1.
