Can i use with metal ball containers or just the plastic ones?

I don't know about your metal containers, however it does not work on all tennis ball containers. The sizes are a bit inconsistent and if it is too loose, then the metal edge sits too low , the plastic screw section bottoms out and has trouble sealing. Too large and you can't screw on the plastic threaded section. Also note that the metal edge on the tennis ball container can contain dents making it hard to seal. I have found one that lets the plastic threaded section split almost touch which keeps the container metal edge high and seal well. This does keep my tennis balls bouncing well as long as I can keep track of them. Don't expect to recover old balls. Internet has several videos of tests that show it doesn't work. I am happy with my unit once I found an optimal container. I keep reusing the same container. If I open new balls or see a container at the courts , I check the container to have a spare.

Does it work with Technifibre containers?

We are not sure, we haven't tested it with Technifibre containers. However, you can use Ball Rescuer to pressurize Technifibre balls in any of the following containers that our product is compatible with: Penn CHAMPIONSHIP REGULAR-DUTY FELT Penn CHAMPIONSHIP EXTRA-DUTY FELT Penn CHAMPIONSHIP EXTRA-DUTY FELT HIGH ALTITUDE Penn COURT 1 Penn TRIBUTE

Which tennis ball tubes work with this device? (It says Penn tubes work, but my Penn tube is too wide)

You may use this device with any of the Tennis ball canisters: * Penn Championship Regular-Duty, Extra-Duty, and High Altitude, * Penn Court 1 * Penn Tribute

Is it normal to see slight pressure drop every couple of days? I used the silicone grease provided, but pressure continues to drop slowly.

Unless you are using with dead balls, you may not notice any drop in pressure. Make sure you are using this device with recommended tennis ball canisters. If you suspect there is a leak, immerse pressurized device with can in water to see where the bubbles are coming from.
