I have a pair of those baby clippers with the magnifier, but my eyes are weird (I've had cataract surgeries in both), so it's hard for me to focus. The magnifier just seems to make things worse.
I trim my babies' nails when I feed them mealies. That distracts them. Keiko is my mello jello, and I can usually get all of her nails with one mealie. Tomoki, if I'm lucky, will let me trim a foot and hand. Hiroshi, if I'm lucky, will let me trim one nail. He's fast with his mealie and immediately tries to climb back in my bra.
There are several techniques that have been offered by our members. One is to roll the glider up in a towel like a burrito, and then pull a hand or foot out, and trim.
Another is to get a nail file and just gently file their nails while they're asleep during the day in a pouch.
Another is to recruit a friend to hold the glider (they're great at alligator rolls) while you trim.
Another is to take the glider to a vet.
The key is to trim while they're the sleepiest (during the day). And follow with treats like a mealie or yogurt drop. You do want to keep the nails trimmed, though. When too long, they can get caught in fabrics, and they could hurt themselves struggling to get free.
