Pretty good DSO for the money.
Pretty good DSO. I haven't had it for long so have not tested all functions. Only complaint is there seems to be +/-2 bits of digitization noise out of 256 bits. I looked through all the settings to see if there was some kind of smoothing function but apparently not. It would be nice to have an adjustable amount of smoothing. Even the ability to select a 2, 4, or 8 bit sliding window would make a big difference for lower frequency waveforms.

Low price, low quality, but may be OK for low speed, low accuracy application
The bearing is very low cost, the balls seem OK, as is the retainer and the outside of the races also seem OK. However, the surface finish in one of the grooves is poor. It does not have the same finely ground surface, is not as deep and shows what is the equivalent of chatter. Quality control is questionable or these are seconds that were rejected. They may be OK for something like a slow moving table with low accuracy requirements, but not for anything high speed or high accuracy. I have attached a few photos, but the "chatter" is only visible when moving the bearing or light source.
Sale was handled well, product was delivered faster than promised, but you get what you pay for.
